Palisot de Beauvois’s figure and description are alike inaccu-

rate of this magnificent flowering tree, and may be accounted for,

as Mr. Bentham observes, by the fact that the characters of his

species described are generally drawn up from mere fragments of

specimens, and that his drawings, made on the spot, of this and

other plants, were destroyed, as M. de Beauvois himself tells

us ;—“la proie des flammes que les soi-disant philanthropes -de

Paris ont allumées @ St. Domingue.” In the figure of the ‘ Flore

d’Oware’ the leaves are made to appear alternate, and the flowers

are reversed upon the rachis and give no idea of their size and

beauty. Schumacher’s description of his Bignonia tulipifera —

proves it to be the same plant as ours, and he speaks correctly —

of the flowers, “as large as the largest tulips.” It is the mis- —

fortune of this plant that it does not bear its blossoms until the —

tree has attained a considerable size, when they are difficult to —

be seen on account of their distance from the spectator, and, in the

present instance, the necessarily crowded state of our great stove,

where it has perfected its blossoms. It was almost by an accident

that they were observed at all. The species is a native of west-

ern tropical Africa. M. de Beauvois found it at Oware. Mr. ~

Osborne, of the Fulham Nursery, raised it from seeds sent to —

him from Ashantee (and to him we are indebted for our plant). —

Schumacher found it in Guinea, and I possess fine specimens

gathered by Mr. Ansell, who was attached to the Niger Expedi- —

tion under the command of Captain Trotter, collected on Stir- —

ling hills, at the confluence of the river, and equally good ones —

gathered by the late Dr. Irving at Abeakouta.

Dzuscr. A éree, said to attain a good size in its native coun-

try, thirty feet high in our stove, much branched above. Leaves

opposite, pinnate, dark green, paler and somewhat silky beneath —

only in the young state, firm and subcoriaceous, a foot to a foot —

and a half long, impari-pinnate. Leaflets about four pairs (ex-

clusive of the terminal one), ovato-lanceolate, acute, quite entire,

penninerved, having at the base, on the upper side, and just above |

the short petiolule, two to three fleshy subglobose glands. Ra-

ceme terminal, corymbose, large, spreading, consisting of eight to

ten rather long and stout-pedicelled, very large, showy flowers.

The curious calye is quite like a spatha, two and a half inches —

long, splitting open on one side for the emission of the corolla, ©

and falcately recurved, leaning, as it were, back from the corolla:

its texture is thick and coriaceous, externally velvety, and of a

dingy-green colour, striated with raised lines, red within. Corolla

at least four inches long, and as much broad, of a rich orange-re

colour, paler within the tube, in form broad-campanulate, yet

_ curved upwards, the ‘ube suddenly contracted at the very base,

where it is attached to the calyx ; singularly ventricose on its

under side, striated; the faux very broad and open; the dim

_ Spreading, nearly equal, of five, broad, ovate, plicate, and some

what undulated segments. Stamens four, included within th

broad tube, spreading, two a little taller than the other two

Anthers of two divergent, lin

opening longitudinally. Ovary ovate, sunk into a large flesh

gland or ring. Style as long as the stamens.

BRUGMANSIA eximia. Hort.

We are indebted to the Messrs. Henderson, of Pine-apple

Place Nursery, for this remarkable plant, which they received

from the Continent under the name of Brugmansia eximia. In

its foliage it presented nothing of the appearance of a Brag-

mansia, or of any of the arborescent species of Datura; and our

astonishment was great when it produced the flower here répre-

sented, in the summer of 1858, to see a corolla having a good

deal the form of, and excelling in size any, Datura or Brugmansia,

yet with a calyx of a very different character, and much more like

that of a Juanulloa, which the foliage and general habit of the

shrub also a good deal resemble: it is also very different from

any described Solandra, save that it has singularly green flowers

like Solandra viridifiora. May it not be a hybrid? But if so,

we cannot guess what are the respective parents. It is to be

lamented that such a noble-sized corolla should have no brilliant

colour to recommend it.

JANUARY Ist, 1859.

Descr. This very peculiar plant, whether it be in its natural

state, or metamorphosed by hybridization, has in its mode of growth

and foliage more of a Juanulloa than of a Brugmansia or any

frutescent Datura, and more still of a So/andra, than which it

forms a much more compact bush; it is moderately branched.

Branches ternate, woody. Leaves large, oval, firm, subcoriaceous,

glossy, shortly acuminate, quite entire, tapering into a stout

petiole about half an inch long. /owers, in our plant, lateral

(not strictly axillary), in pairs, very large, drooping. Peduncle

scarcely an inch long, stout, curved downwards. Calyx broad-

ovate and an inch and three-quarters long and as much broad,

of a thick, subcoriaceous texture, very broad-ovate, five-valved

and five-angled, in bud sharply so at the sinus; estivation val-

vate, bursting irregularly into five acute lobes of unequal lengths,

sometimes two or more continuing adherent at the margin (as in

Juanulloa). Corolla nearly six inches long, and quite as broad

across the limb, if allowance be made for the recurvation of its

lobes; the form is between infundibuliform and campanulate ;

the colour quite green, but with a peculiar tinge of yellow upon

it; the tube has five longitudinal angles, and, alternating with

these, five lesser ones ; the mouth spreads widely ; the limb has

five broad but sharply acuminate, quite revolute odes, each

with three impressed lines or longitudinal plaits. Stamens five.

Filaments erect and approximate, a little longer than the tube,

so that the linear anthers, an inch long, are quite exserted. Ovary

broad-ovate, surrounded by a fleshy ring. Style filiform, quite

as long as the filaments of the stamens. Stigma an inch long,

incrassated, bifid, the apices of the lobes spreading.

Sansgeviera Angolensis. Wellwitsch, MSS.

About three years since there were received at the Foreign

Office, and transferred to the Admiralty, samples of a peculiar

fibre and cordage under the name of //¢, said to be derived from

a new plant at the Portuguese settlement, Angola, west coast of

Africa. These were accompanied by some apparently living

plants, which were placed in the cellars of the Foreign Office,

and by the kindness of our valued friend, G. Lenox-Coningham,

Esq., forwarded to Kew, where they soon recovered, and have

since flowered. The habit of the plant was that of Sanseviera,

but the leaves very dark-coloured, and quite terete and solid in

the interior, very unlike any known species of that genus. My

duties at the Paris Exhibition of 1858 led me to the careful in-

JANUARY Ist, 1859.

vestigation of the vegetable products, and I was there agreeably

surprised to find most extensive samples, in the Portuguese de-

partment, of the raw material, fibre, and manufactured articles,

ship-cables, rope, beautiful cordage, etc., of the same material,

and amongst ‘The Products of Angola,’ it is thus stated in my

‘Report :'—“ Fibre, marked, from Sanseviera Angolensis, this

latter being a MS. name of Dr. Wellwitsch for a remarkable spe-

cies of Sanseviera, with long, stout, terete leaves, which is in culti-

vation at Kew. The cordage and rope made of this plant appear

to the eye of excellent quality, whatever experience may prove

them to be.”"—Experiments recently made with this cordage have

shown it to be the strongest and best fitted for deep-sea sound-

_ ing of any fibre known ; indeed this is the less surprising, seeing

that other species of Sanseviera (the well-known S. Zeylanica and

Guineensis, for example) are cultivated in almost all tropical —

countries on account of the strength and durability of the fibre,

under the name of Bowstring Hemp.

Our Gardens having lately received from Mauritius, through

Mr. Duncan, living roots of 8. cylindrica of Bojer, in the

‘Hortus Mauritianus,’ without note or description, I have been

agreeably surprised to find that the two plants are identical. It

is indeed stated that the 8. cylindrica is a native of Zanzibar,

on the east coast of* Africa, and is only known in cultivation in

the Botanic Gardens of Mauritius. I have no means then of

ascertaining whether this curious plant has been introduced by —

the Portuguese from their settlements on the east coast of Africa —

to Angola on the west, or vice versd; or whether, as appears to

be the case with other plants, it is an aboriginal on both sides of —

that great continent, and more or less, possibly, of the interior. —

Dr. Livingstone told me he was very familiar with the J/é in se- _

veral districts of the western interior of Africa towards Angola. —

It flowered with us for the first time in August, 1858, and.

though the blossoms have little to recommend them, the plant

deserves a place in all collections where the useful products of 4

vegetables are appreciated, and many a piece of waste land nm —

our tropical colonies might be profitably employed in the cultiva- x

ok of it for its fibre. It grows rapidly, and requires almost no aa

Desor. Perennial. Roots coarse and fleshy. Plants throwing ’

out runners from the base and gs |

rs fr eedily sendin oots.

Leaves all radical, tufted, few, nb tian eight Pain tuft, —

and not so many unless the short, external ones, which almost

resemble scales and are more or less furrowed on the upper side,

be reckoned ; the rest vary in length, from six to eight inches

to three feet, erect or erecto-patent, quite terete, solid within,

oceupied by firm, fleshy, cellular matter and copious fibre, of

dark-green colour, externally sometimes a little glaucous, and not

unfrequently banded transversely with paler lines, acuminated,

a little compressed at its apex, now and then longitudinally fur-

rowed with three or four shallow lines. Scape, below the flowers,

eight to ten inches or more long, shorter than the leaves.

ftaceme a toot or more in length, tapering upwards, having fas-

cicles of numerous flowers all along the rachis. Bracts small,

very deciduous. Perianth of six, narrow-linear, very long,

cream-white sepals, tinged with pink; rather more than the

lower half of them is erect and approximate, so as to form a

tube, but eventually separating, and soon deciduous ; the rest are

revolute. S/amens very much exserted, twice as long as the

tube of the perianth. Filaments slender. Anthers linear, pale-

yellow. Ovary oblong, trigonous, three-celled. Ce//s one-seeded.

Style filitorm, longer than the stamens. Stigma capitate, three-

lobed.

Native of Madagascar, and probably common enough there

(as we have received native specimens from thence, from the late

Professor Bojer, from Dr. Lyall, and also from M. Bouton) ; yet

when one knows the beauty of this plant and the difficulty of

obtaining any plants from that fertile region, one cannot be too

thankful to the Rev. William Ellis* for having introduced this

species of Zisianthus in South America, and in those of Zuchia-

danthus m Madagascar. A clever drawing by Mrs. Ellis (from

which our plate is copied), accompanied by a recent flowering

specimen, was sent from the garden at Hoddesdon in October,

1858, raised by Mr. Ellis from seeds brought home with him.

The five species of this genus hitherto described by authors,

have been considered to have white flowers, but this was only

inferred from the withered corollas in dried specimens. ‘They

are probably all purple or blue-purple, and of a peculiar rich

to these is also an axillary pair of flowers. Pedicel shorter than

the leaf. Calya oblong, with five linear, subulate, carinated lobes,

from the back of each of which a winged angle extends to the

base of the calyx. Corolla hypocrateriform, with a very long,

slender, white ttibe, two to three inches long, a little enlarged

upwards ; /imb spreading horizontally, rich purple, of five imbri-

The ordinary form of this plant is given at our Tab. 508 (in a

very carly volume of the ‘ Botanical Magazine), soon after the

seeds were sent by M. Broussonet from the coast of Barbary to

Mr. Aiton, at the Royal Gardens of Kew, almost sixty years ago.

It has proved to be a hardy annual; and, even in its original

state, on account of the large size of the flowers, the dark-purple _

eye, and the white rays, yellow at the base, it was spoken of by —

Mr. Curtis as “the beautiful Chrysanthemum ;” and he gave it

the name of C. ¢ricolor, without being aware that it was pre-

viously described by Schousboe, under that of C. carinatum, so

called on account of the remarkable green, fleshy keel at the

JANUARY Ist, 1859.

back of each membranaceous scale of the involucre. Cassini

constituted of this a new genus, Ismelia, on very slight grounds,

and then very unnecessarily changed the specific appellation to

the no less appropriate one of versicolor. Curtis and others had

observed that the rays of the corolla were sometimes wholly

yellow. Mr. William Thompson, of Ipswich, has sent to us du-

ring, the summer of 1858 the singularly. beautiful varieties here

figured, which were raised by Mr. K. Burridge, Lexden Road,

Colchester. We have seldom seen a richer combination of co-

lour than is exhibited in these flowers ; and if the seed is found

to continue constant to its parent, no flower-border ought to be

without this variety.

The genus Fuchsia includes a considerable number of species,

but the difficulty of naming them correctly is, beyond anything, ©

great ; and this difficulty arises in part from the liability of these

plants to vary much in their inflorescence, size, and the shape as

the flowers, and in part from brief and imperfect descript:

The present species is one of the many beautiful Peruviai a5

new to our collections, which Mr. William Lobb sent to his em- —

ployers, Messrs. Veitch and Son, of the Nurseries at Exeter and

Chelsea, and which in many respects corresponds with the 7.

simplicicaulis of Ruiz and Pavon; the flowers quite correspond

in size and shape, and the whorl of flowers is subtended by a

corresponding whorl of large foliaceous bractes, or small leaves ;

but in Ruiz and Pavon’s plant the leaves and the bracteas are all

lanceolate, and even rather narrow-lanceolate, and the whorls are

figured and described as always quaternate, whereas in our plant

the leaves and bracts are ternate, and rather ovate than lanceo-

late, and the latter close over the pedicels so as to form a cup-

Shaped involucre. Some of our native dried specimens, indeed,

sufficiently accord with Ruiz and Pavon’s plant; but others

Pavon’s figure represents it so (spite of the specific name), and

even with verticillate branches, as might be expected to occur;

and P.) on the main stem and branches, four to five inches long,

much smaller upon the pendulous, elongated, flowering branches,

where they become bracteiform, but spreading; their form is

ovate, approaching to lanceolate, a little polished above, entire,

on very short petioles, those of the bracts sessile. Flowers large,

handsome, numerous, rose-scarlet, one in the axil of each floral

leaf or bractea, pendent. Pedicels short. Ovary oval. Tube

of the calye long, infundibuliform ; the segments spreading, four,

lanceolate. Petals ovate, acute (red), shorter than the sepals.

Stamens exserted, but moderately so.

The true Agave lurida of Hortus Kewensis, ed. 1. v. 1. p. 472,

and ed. 2. v. 2. p. 302, is figured and described by Mr. Gawler

(Bot. Mag. t. 1522) from the original Kew plant, which has

since died. This is the Agave Vera-Cruz of Miller, Gard. Dict.

ed. 8. n. 7; and Mr. Gawler has accurately pointed out the dif-

ferences between this plant and the dyave lurida of Jacquin 's

‘Collectanea Botanica,’ v. 4. p. 92. t. 1. _ In the original Agave

lurida the flowers are lax and distant, twice the size of those of

Jacquin’s Agave; the tube (with the adnate ovary) 1s ~

elongato-cylindrical, constricted above the base, longer than

sepals, which are broad-lanceolate, acuminate, concave, and spread-

ing; the filaments of the stamens are quite erect, and green as

well as the anthers. Jacquin’s Agave has densely crowded

flowers, the ovary six-furrowed, shorter than the sepals, which

latter are quite erect and almost connivent, the stamens are

spreading and yellow, and the peduncles are soboliferous or

viviparous. About ten or twelve years since, we received an

FEBRUARY Ist, 1859.

Agave from Mrs. M‘Donald, of Honduras (which accompanied

the noble-flowered Cereus Macdonaldia, Bot. Mag. t. 4707);

and this, upon flowering in our Palm-house, in the autumn of

1858, corresponded in every particular with the figured descrip-

tion of Jacquin. That Ayave, Schultes, in accordance with the

views expressed by Mr. Gawler, has named Agave Jacquini-

ana. The fruit too, which is now (Jan. 1859) fully formed, pre-

cisely accords with that figured in the ‘Collectanea Botanica,

and that fruit is not a little remarkable, being exactly urceolate,

with a very contracted neck.

The above remarks may serve as a substitute for any long or

tedious description. :

Duscr. Stem ascending, a foot and a half high, scarred with

the remains of fallen leaves. The perfect leaves form a crown,

and are from two and a half to three feet long, narrow-lanceolate,

pungently acuminate, spreading in all directions, the superior

and younger ones erect, the middle ones horizontal, the infe-

rior ones reflexed, remotely dentato-spinose with curved spines.

Scape about twelve feet long, stout in proportion, quite erect,

firm and rigid, almost scaly with withered bracteas. Panicle

compound. Pedicels stout, dichotomously divided. lowers

geminate or ternate, bracteolate, some quite sessile. Perianth

quite green, little more than two inches long; the tubular portion

1s oblong-oval, six-furrowed ; the free portion, or sepals, more than

half as long again as the tube, linear-oblong, channelled, obtuse, —

quite erect, and connivent, pressing as it were against the yellow,

much exserted stamens ; these stamens are twice as long as the

sepals, spreading. Anthers very large, full-yellow, versatile. Style

_ as long as the filaments. Stigma obscurely three-lobed. Fruit, —

or capsule, when fully formed, an inch and a half long, urceolate, —

almost black when ripe, with a very contracted neck, three-

ett three-valved, containing in each cell several black angular —

eeds. :

The Hibiscus radiatus, of which the ordinary state is to have

sulphur-coloured petals, was first described and figured by Ca-

vanilles, in 1780, from plants of which the seeds were sent by

Sir Joseph Banks to that distinguished Spanish botanist ; but

Cavanilles does not state from what country they were received,

or where a native. Willdenow gives no locality. Aiton, in the

second edition of ‘ Hortus Kewensis,’ speaks of it as an East

Indian species; but Roxburgh seems only to have known it in

gardens, observing, “ Native place unknown. Common in gar-

dens about Calcutta, where it blossoms during the cold season.

Wight and Arnott also, in their ‘ Flora of the Peninsula of India,

give no locality, quoting Roxburgh’s statement on this subject,

and adding, “ In Dr. Arnott’s herbarium 1s @ specimen from Ja-

maica.” So that some have been led to suppose it was a West

Indian plant ; and certain it is, we have received specimens from

Jamaica, but without any special locality ; and of late Mr. Wil-

son, the intelligent superintendent of the late Botanic Garden at

Bath, in that island (I say /afe, an awful flood having recently

overwhelmed the garden with an avalanche of stones), has sent

iful, and all distinguished

to us seeds of three varieties, all beaut

FEBRUARY Ist, 1859.

above alluded to ; the second is the one we figure here, of a fine ©

rose-purple ; and a third is a full blood-purple; but in each of —

these two last-mentioned kinds the base of the petals is of a still —

deeper purple tinge, forming an eye-like spot to the centre of the

entire flower. The three sorts blossom copiously in the stove,

and bear a succession of flowers in the summer months. We |

are still in ignorance as to whether this species is aboriginal in —

Jamaica. Certain it is that we do not find it anywhere recorded —

as a native of the West Indian Islands, nor even noticed in any

of the Floras of that quarter of the globe.

About the year 1846, we received from Mr. Repper, of the

Real del Monte Company’s establishment, Mexico, some re-

markable plants.in the form of tubers, a foot and half long, and

nearly as high aboveground, the surface of which is formed by

a number of wrinkled tubercles, slightly elevated, and somewhat

circinately wrinkled ; from a few of which appeared tufts of rigid,

subulate leaves, one to two feet long, in form and texture resem-

bling those of some Dasylirium. The general aspect of the tubers

reminded one of the well-known “ Elephant’s-foot” of South

Africa, or of some remarkable Dioscoree which we cultivate from

Mexico. These remained dormant for some years, but one of

them has lately produced more copious tufts of foliage and panicles

of flowers ; and precisely accord (the female flowers are however

wanting to our plants) with the Dasylirium Hartwegianum of

Zuccarini, which Hartweg sent from Zacatecas, in Mexico ; and

a Dasylirium of Mr. Charles Wright (“ Coll. N. Mex. 1851-2”),

n. 1918, also seems to be identical; but neither of these collec-

tors has made a note on the nature of the plant ; so that whether

FEBRUARY Ist, 1859.

we are to consider this tuber as the normal condition of the stem

or caudex of this species, or whether we are to look upon it as

an accidental collection or congeries of united stems (a kind

of monstrosity), still remains a doubt in our minds. All the

Dasyliria yet known to us have separate, unbranched, and dis-

tinct stems, more or less elongated, as in the caulescent species

of Agave, and as may be seen in our figures of two of the

species of this remarkable genus, at our ab. 5030 and Tab.

5041. The flowers of the panicles develope themselves very

slowly, and the withered stalks and branches remain a long time

attached to the trunk. Mr. Bentham compares this plant with

the Cordyline longifolia of H.B.K.; but the very large, almost

sheathing bracteas, rather than leaves (which latter do not appear

in the figure given by Humboldt), and the widely different ra-

mification of the panicle, and the acuminated sepals, indicate

something very different.

Descr. Caudex a gigantic tuber, as above described; from

the tubercles on the surface of this, the tufts or fascicles of /eaves

appear, from one and a half to three feet long, slender, harsh and

. rigid, from a rather broad lanceolate base, gradually becoming

subulate, and tapering to a very long, slender, rigid, pungent and

entire point ; of a glaucous hue, finely striated, moderately keeled

at the back, canaliculate on the upper surface, the margin rough

to the touch from the presence of rather distant, curved, spi-

nescent teeth, pointing upwards, uniform (not of two kinds as

in D. glaucophyllum and D. acrotrichum); at the base behind a —

broad costa is seen, transversely wrinkled. From the centre of

the tuft or fascicle of leaves the panicle arises, shorter than the

leaves, scarcely more than a foot or a foot and a half high,

branched from near the base; primary dranches spreading hori-

zontally, distant, quite straight, rigid; the inferior ones with

long subulate dracteas at their base; the rest with small palea-

ceous ones. Flowers in glomerules or clusters upon the straight

branches, rather lax, bracteolate. Broader and quite membra-

coreg bracteoles (about three) surround each pedicel, which

atter 1s about the length of the bracteoles, and jointed at the

summit, whence the flowers readily fall away. Sepals orbiculari-

elliptical, membranaceous, white at the edge, the rest purplish.

Stamens (our plant has only male flowers) six, longer than the

penianth ; filament subulate. Anther subcordate.

A very handsome plant of the Cactus family, whose large flow-

ers are highly fragrant. The species belongs to a group of the

old genus Cactus, which have the large and long tube of the

Cereus group, but with singularly compressed and almost leaf-

like, more or less lobed stems and branches. ‘To this division

belongs the Cereus phyllanthovdes, DC. (Bot. Mag. t. 2092);

Cereus Akermanni, Pft. (Bot. Mag. t. 3598); Cereus phyllan-

thus (Hook. Bot. Mag. t. 2692), ete. ; and these now constitute

the genus Phyllocactus of Link. Five species are enumerated by

the Prince of Salm-Dyck in his useful ‘ Cacteze in Horto Dyck-

ensi culte, anno 1849.’ Since the publication of that work,

the present species has been imported from Western Mexico, —

and received from M. Lemaire the name of anguliger, from the

numerous lobes of the flattened stems, many of them, forming

very nearly rectangular triangles. We received our living plant

This is certainly the most lovely of the many lovely species of

Begonia with which we are acquainted, and almost justifies the

laudatory notice M. Van Houtte has given of it in the volume

just quoted: “Nous sommes bien désolé d’arriver si tard a faire

paraitre la planche représentant de demi-grandeur* la feuille du

Begonia Rex. Ainsi que vient de le dire M. J ules Putzeys,

notre honorable collaborateur, c’est a M. J. Linden qu est échue

la bonne fortune d’augmenter les collections Europeennes de ce

merveille Begonia, dont la venue est tout un événement en hor-

ticulture. En ayant acquis de nombreux exemplaires des la

mise en vente, nous avons pu en réserver quelques-uns pour

en faire des spécimens, qui, pendant le cours du dernier été,

produisirent sur les visiteurs un de ces effets saisissants qui char-

ment tout autant le vendeur que I’acheteur. Le débit a été

grand; mais aussi est-ce la une de ces plantes ‘fit for the million,

comme disent nos confréres de la fire Albion.”

Mr. Linden is stated to have received the plant from Assam ;

but it is not to be supposed the enormous size of the leaf repre-

sented by M. Van Houtte is natural to it in its own country,

* This “ demi-grandeur” is 14 inches long and 93 wide!

FEBRUARY lst, 1859.

—it is the effect of high cultivation; and what is gained in

size is lost in brilliancy of colour, to judge from the figure. It —

has flowered with us in the autumn, and probably by a little

management the blossoms may be produced at most seasons of

the year.

Descr. There is no true stem to this plant. The red, terete —

petioles, furrowed on the anterior side, spring in clusters from a —

subterraneous creeping rhizome, by dividing which the plant is —

readily increased. Bracteas ovate, hair-pointed, strongly ciliated

at the lower edge. Leaf about as long as the petiole, in our plants

averaging eight to ten inches long, five or six broad, obliquely and —

inequilaterally ovate, deeply cordate at the base, the lobes over-

vanthina, above quoted, and at present at least, till I can learn

more of its history, I am disposed to consider it a variety of

that plant, or perhaps a cross with some of the painted-leaved

species. It is, indeed, near akin to B. Rex (see our Tab. 5101),

especially in the leaves; but that has yellowish-white flowers,

tinged with rose: all of them have mucronate anthers. I fear

much dependence cannot be placed on the colour of the flowers,

nor on the spotting of the leaves. Some of our own young

present plant belongs to the same group as Lpigyniwm acumt-

natum, K\., figured at Tab. 5010 of our volume for 1857, and

we are indebted for the introduction of it to our greenhouses

to the same venerable botanist as for that, Mr. Nuttall. It was

imported living from the Duppla Hills, north-eastern Bengal,

by his nephew Mr. Booth, who found it there growing on a

species of Oak. “It is an evergreen shrub,” writes Mr. N uttall,

“seven or eight feet high, very erect, with verticillate branches,

a tuberous root, almost like that of a yam, but harder in sub-

Stance, having numerous racemes of white, conic, pentagonal

flowers, so diaphanous as (when held between the eye and the

light) to show the ten, yellow, awned anthers within. It proves

a hardy greenhouse shrub, bearing its pure-white flowers most

copiously in the summer months, and its equally white and

wax-like berries (reminding one of the “crow-berries ") in the

autumn.

with five dark spots in a circle below the apex, which are the

remains of the small calyx, five-celled.

“ from some part of India.” It is assuredly among the prettiest

of a very pretty genus, and when first exhibited at a meeting of |

the Horticultural Society, in 1854, “ excited the admiration of

everybody present.” It seems by no means difficult of cultiva-

of flowers increases the vigour of the plant, and the brightness

of the foliage. We are indebted to Mr. Veitch for our living

This very interesting species of Palm has flowered at the Royal

Gardens, Kew, recently, for the second time ; plants having been

sent to us many years ago by the late Dr. Wallich, under the

name of Zalacca Assamica, Wall. MSS. This same plant Grif-

fith has, in the ‘Calcutta Journal of Natural History, properly

referred to the genus Plectocomia, and has distinguished it, with

little care or accuracy, from the P: elongata of Martius and

Blume. Griffith has, indeed, figured and described (very imper-

MARCH lst, 1859.

fectly) what he considers two other species of the genus, which

he has named after the countries in which he found them, P.

Khasiyana, and P. Himalayana. Of P. Assamica he observes,

“The fruit is a good deal like that of P. elongata, judging from

Martius’s figure, but the scales are so fimbriate that it has quite

a woolly appearance.” Under P. Khasiyana he remarks, “ This

would appear nearly allied to the preceding (P. Assamica), from

which it differs in the smaller spathas, the very small calyx, with

minute triangular teeth, the broader petals, the brown, not rust-

coloured fruit, which is smaller, and not by any means so villous,

the points of the scales being less fimbriate, and often deciduous.”

Of P. Himalayana,* “This may be the male of the preceding

' (P. Khasiyana).” The figures too, such as they are, sufficiently

represent our plant to justify me in quoting them, though doubt-

fully. The P. Mueller, Bl., of Java, seems to be a very diffe-

rent species, detected also in Borneo by Mr. Thomas Lobb.

Our present kind seems peculiar to Eastern Bengal, and differs

from P. elongata in the long, lax-coloured (white, brown, and

green), narrower spathas, the very long acuminated segments of

the corolla, and in the constantly more numerous stamens. It

is a slender Palm, attaining the length of sixty-six feet, even in

cultivation in our Palm-stove, and though not strictly scandent,

needing support; and Nature has admirably provided for this

want by the curious and excessively strong, digitate spines upon

the rachis of the frond, in shape resembling the foot of a mole.

A singular use is made of that of the allied Plectocomia elongata

in Java (as witnessed by the late Mr. Winterbottom), by persons

whose duty it is to catch rogues and vagabonds. ‘To the inside

of a forked stick a sufficient portion of the rachis is attached,

with its strong deflexed spines; and this fork being thrust in

such a way as to include the body of the man, the spines get a

firm hold of the captive, either by his clothes, or what is much

more painful, his flesh. The leaves or fronds are said to be em-

ployed for basket-work.

Duscr. Caudex very long, ragged with the very spinous

sheathing bases of fallen leaves ; below, the caudex is scarcely so

thick as a man’s ankle, but it becomes a little broader upwards ;

the upper portion, and for a considerable length below the apex,

leafy. Leaves or fronds often thirty feet long, but the lower half

only is pinnated ; the rest is a flagelliform extension of the rachis,

destitute of pinne, and the whole flattened under side of this

rachis is beset with stout, compound, digitate spines, at greater

or less distances, all pointing downwards: those nearest the base

of the leaves are longest and straightest. It is stated that by

means of these spines the fronds hook themselves on to the

branches of trees, and so maintain the trunk in a nearly per-

pendicular position. Pimze@ numerous,.six to seven inches to

nearly a foot long, more or less broadly lanceolate, acuminate,

plicate, very glaucous beneath. Spadices (male, the only ones I

have seen living) are numerous from among the leaves, com-

pound, that is branching from near the peduncle, and these

branches long (two and three feet or more), gracefully drooping,

pendulous; they are clothed with numerous, imbricated, disti-

chous scales or spathas, two to three inches long, subrhombeo-

oblong, carinate, concave, firm-membranaceous, acute rather than -

acuminate, nearly white, with a band of pale-brown below the

green apex, which is often tinged with dark-brown, and finely

ciliated at the margin. Within each spatha is a spike (or parteal

spadiz) of numerous, pale-yellowish, bracteolated flowers. Calyx

trifid, with the lobes or teeth subulate. Corolla tripartite; seg-

ments long-lanceolate, acuminate. Stamens eight to ten or twelve,

much shorter than the corolla. Filaments short. Anther linear-

oblong, subsagittate. Female spatha (from our first flowering

specimen) similar to the male.. Spike or partial spadix ot Semale

flowers about one-half the length of the spatha. Calya large

in proportion to the flower, three-lobed; the /odes obtuse, mu- —

subglobose, clothed with reflexed, fringed scales. Style short.

_ Stigmas three, fringed in the inner face. Fruit (seen only in the

dried state) globose, brown, an inch broad, clothed with reflexed,

fringed scales, subtended by the persistent and very rigid floral

coverings. Seed globose. Albumen firm and hard, copious.

Mr. Linden, the distinguished horticulturist at Brussels, has

great merit in having of late years introduced to our Euro-

pean stoves a series of plants of the genus ot eae “from Assam,

of very great beauty, both in respect o flower and foliage ;

the latter remarkable for its great size and metallic lustre,

and exhibiting, in these leaves, a considerable variety both in

the nature and disposition of the spots. To this group belong

the Begonia Rex (see our Tab. 5101), the Begoma amabilis,

argentea, and Victoria, of Linden, and B: Lazuli of the same

author (the plant here figured); all these belong to one and the

same group, of which our B. 2anthina (Bot. Mag. t. 4683) from

Bhotan may be considered the type, if it be not, as I am in-

duced to suppose it is, the common parent of all, assisted, as

may probably be the case with the Begonia Rez, by a cross

with some pink-flowered species. Indeed the B. Victoria of

Linden (as it proves to be, see our Tab. 5102) I had no hesita-

tion in considering as a painted-leaved variety of B. vanthina,

and I have as little in referring our present plant to that also.

But it deserves a place in every ornamental stove as much as if

it were a distinct species. Linden himself alludes to the analogy

in question. “Sans avoir la prétention de se comparer a lespéce

As compared with the noble pitchers of Nepenthgs Raflesvana,

Jack (see our Tab. 4285 of this work), and our still more striking

Nepenthes villosa,* given at Tab. 5080, NV. ampullaria claims few

attractions ; and it has unfortunately happened that our artist took

his drawing too late in the season for the more perfect pitchers,

which are collected in numbers about the base of the plant at

an earlier season, on small and abortive leaves, and then disap-

pear. These are sometimes almost globose, singularly inflated

or ampullaceous, whilst the pitchers springing from the end of a

fully-formed cauline leaf, where they are always less perfect, are

narrower and oval-oblong; and no others were present on the

plant at the flowering-season (August). The species 1s a native

of the forests of Singapore ; also at Rhio, on the island of Bin-

tang, Malay Archipelago. We owe our plants to the liberality

of Lady Dorothy Nevill; Dangstein, and of Messrs. Veitch and

and that, together with the lower portion of the erect and scan-

dent stem, bears whorls of abortive or very imperfect leaves, ter-

minated by an inflated, broad, ampullaceous pitcher, three inches

long, green, membranaceous, sometimes faintly tinged with red, —

obliquely striated, slightly contracted above; the mouth at first

small, and closed with an oblong or lanceolate lid, which soon

opens, and becomes erect, at length reflexed ; bearing just above

the base a soft bristle. Leaves on the stem remote, broad-

lanceolate, sessile, costate, with a few lateral, longitudinal veins,

and several transverse ones; these leaves are terminated by a

filament (or prolongation of the costa), either clubbed at the apex

or bearing a pitcher, narrower and more cylindrical than those

just described. Female plant: panicle or raceme downy, bear-

ing flowers similar in structure to those of other species already

described.

ceous Jobe, similar to what takes place (except in respect of co-

lour) in the well-known Mussenda of our stoves. It is a plant,

too, interesting in another point of view, as one of a new ge-

nus of which the typical species, Howardia febrifuga, Weddell,

of Bolivia, has been detected as one of the medicinal barks of

commerce, and much used by the Bolivians in intermittent

fevers.* To this plant Dr. Weddell has assigned the generic name

Howardia. “Parmi les genres,” says Dr. Weddell, “que jai

fait connaitre dans ma Monographie des Quinquinas, il en est un

auquel jappliquai, par mégarde, un nom (Chrysoxylon) apparte-

nant a une plante d’une autre famille. Pour mettre fin 4 ce double

emploi, je vais aujourd’hui donner 4 ma Rubiacée un nom nou-

veau ; et je ne fais, ce me semble, qu’un acte de justice en lais-

sant tomber mon choix sur celui de l’excellent quinologiste qui

vient de publier, en Angleterre, un mémoire aussi judicieux

qu approfondi, sur la collection de Quinquinas de José Pavon,

léguée par Lambert au Musée Britannique.” No compliment

could be better deserved. Another described plant referred to

this genus by M. Weddell is the Calycophyllum tubulosum of

De Candolle, from Brazil. A third species is the Howardia

grandiflora, Weddell, readily distinguished by its linear calycine

teeth; and a fourth species is the Howardia Caracasensis, cer-

tainly our plant of Venezuela, but so nearly allied to Howardia

tubulosa that Dr. Seemann has united the two, as well as a

Peruvian species in my herbaria, which latter, I think, will prove

different. :

Howardia Caracasensis, as its name implies, is a native of the

province of Caracas, in Venezucla, where it was detected by

FPuncke (P\. Exsice. n. 463, in Herb. Paris., n. 372, Herb. Hook.).

We possess specimens also from Fender, from the shme country,

and from our collector, 47. Birschell, and from the banks of the

river Chagres, in Panama, gathered by Seemann.

considered that of the really good and distinct kinds. The

genus required weeding ; and our friend Dr. Planchon has done

great service to the cause of botany in his’ excellent Revisio

Ordinis Linearum,’ and this he has elaborated with great in-

dustry and perseverance in the ‘ London Journal of Botany

above quoted. I cannot do better than copy his character and

has established after a careful examination of Russel’s original

species in the Banksian Herbarium. The specific character

above introduced, and the accompanying figure, render any more

minute description needless. The species seems to have an ex-

tensive range,—Aleppo, Mount Lebanon (Herb. Hook.), Sicily,

throughout Greece and the Greek islands, in Macedonia and

Bithynia, at elevations of fifteen hundred to seventeen hundred

feet above the level of the sea.

The seeds from which our plant were raised, were received

from M. Reuter, collected in the plain of Mersina, Cilicia. It

is a pretty hardy annual, but the flowers are sadly wanting in

that brilliancy of colour which renders the Linum grandiflorum

(see our Tab. 4956) such a favourite in our gardens.

I spoke of the Angrecum eburneum (see our Tab. 4761) with

admiration on account of its noble aspect. But it shrinks into

insignificance in comparison with the present Madagascar rarity,

known to botanists only through the figures above quoted of

Aubert du Petit-Thouars (published about 1822), till the Rev.

William Ellis, the distinguished traveller and historian of Mada-

gascar, on his last return from that wonderful island, made us

acquainted with the living plant, which that gentleman has twice

flowered, first in 1857 , when the interesting account and figure ap-

peared in the ‘ Gardeners’ Chronicle,’ and now again in the winter

(February) of 1859, at his residence, Hoddesdon, Herts. ‘There

our figure was taken, and though not one of the figures quoted,

not even the original ones of Du Petit-Thouars (though there

* In neither of these two works of M. Aubert du Petit-Thouars is there any

description of the plant. The first of them stops short at the thirty-second page,

and before any descriptive matter of the genera and species appears, and Pritzel

notices this deficiency. Of the second work, in large folio, with six coloured

figures of Orchideous plants of Madagascar (presented to me by the author, and

length of the spur. The former, in the specimen before us,

measures seven inches across, and the spur one foot in length,

so that if the spur were set on at the edge of the flower, instead

of the middle, it would rather exceed than fall short of the size

attributed to it. ‘This flower is of a uniform, pure ivory or yel-

lowish white, and it has the merit of possessing the odour of

the white Garden Lily, Lilivm candidum. The plant continually

attracted the attention of Mr. Ellis as he travelled through its

native woods; more than one of his photographs includes trunks

of trees loaded with this prince of Orchideous plants, and it is

frequently the subject of his description and admiration. Indeed

no one has travelled in tropical regions, possessed of a greater

love of nature, especially of vegetable forms, than this gentle-

man. It should be borne in mind also that he introduced to our

stoves the still more remarkable Lace-leaf, Ouvirandra fenestralis,

and other rarities.

as the plant,—simple or bearing one or two branches; attached

to the trunks of trees by wiry fibres, rather densely clothed with

distichous, spreading, more or less recurved leaves, of a broad

oblong form, thick and fleshy, dark-green, imbricated, carinated

at the base. Peduncles solitary, axillary, bearing from two to

four gigantic ivory-white fragrant flowers, each subtended, at

the base of the ovary, by a broad, ovate, coloured dract. Sepals

and petals equally spreading, nearly uniform, three inches long,

from a broad base, gradually acuminated, somewhat fleshy. Lap

equal in size with sepals and petals, from a cordate base, ovate,

acuminated, near the middle, on each side, coarsely and irregu-

larly serrated ; from the base of this, beneath, depends the very

long, terete, but gradually tapering spur, one foot in length, green

in colour. Column very short, thick, with two broad wavy wings

on each side the stigma, which almost conceal that organ. A”-

margin. Pol/en-masses two, ovate, waxy, each attached to a

somewhat linear gland.

——

Notwithstanding that the ‘Botanical Magazine ’ exhibits two —

figures of this species of Gesneria already, yet I venture to give ©

a third ; firstly, because this fine variety richly deserves a place ;

secondly, because it gives an opportunity of correcting errors of

my own, and, as I conceive, those of my friends also, who have |

treated on this plant. The first appearance of it in the ‘ Maga-

zine’ is at Tab. 2776, under the name of Gesneria verticillata,

from a very weak plant, with only two terminal flowers, which the

late Mrs. Arnold Harrison received from hills about Rio Janeiro.

The previous year, namely, in 1826, Dr. Lindley had named,

what he was afterwards led to consider the same plant, G. Dou-

glasii ;—the name of G. verticillata, too, having been previously

occupied by a plant of Cavanilles. This plant of Lindley is well

figured in Bot. Reg. t. 1110; and since by Van Houtte and

Loddiges, under the correct name of Douglasit. A remarkably

fine specimen of my G. verticillata, imported by Mr. Alleard, from

MAY Ist, 1859. ;

Rio, was sent to me in 1836, and finding it to differ from Lind-

ley’s G. Douglasit in the peculiarly verticillate and generally

simple peduncules of the flowers, I called it G. Douglasii, var.

verticilata ; and I remarked,—* In Professor Lindley’s plant the

inflorescence is a decided panicle; in ours the peduncles, gene- —

rally simple, are arranged in dense whorls, many of them quite

simple, others very slightly branched, and only near the base.

- Our flowers too are larger than in that figure, and more inclining

to a purple tint.” I may here add that in our plant the corolla

is subclavate and decidedly curved; in Lindley’s plant the tube

is quite straight, and the limb more patent.

During the present winter my attention has been directed to

a state or variety of this plant, which has been the pride and

ornament of our stoves during the winter months. Of it we re-

ceived the tubers from Mr. Millosovich, of Rio Janeiro, last year ;

and I was not a little surprised to find it taken up as a new spe-

cies, both by Dr. Lindley, in Paxton’s ‘ Flower Garden,’ under

the name of G. purpurea; and by Dr. Planchon, in the ‘ Flore des

Serres,’ under that of Dirceo-Gesneria purpurea; the former,

its introduction being unknown to him, suspects it to be a hy-

brid, “ perhaps between G@. Douglasii and G. discolor ;’”’ the latter

traces its parentage, but unaccompanied by any proof, to Ges-

neria Douglasii and G. (Dircea) lobulata (a rich scarlet-flowered

species) of both of which excellent figures are given by the

author in the same volume. ‘To Dr. Lindley is due the merit of

distinguishing the G. purpurea as a species; and since I am

able to prove that this has been imported three different times

and by as many different persons, direct from the Brazils, I think

a legitimate parentage will be henceforth conceded to it. I may

add too that my herbarium possesses native specimens of both

the species now under consderation, gathered by Gardner, in

Brazil, and exhibiting all the characters, as figured and described

by Lindley. The one is n. 251, of Gardner’s Herb. Bras., from

the trunks of trees, on the Pedra Bonita Tejuca, 1836, and cor-

- rectly named “ Gesneria Douglasii, Lindl.” The other is his

n. 466, from the Organ Mountains, marked Gesnerie gp. “At

all events,” Dr. Lindley concludes, “ G. purpurea is one of the

most striking of the whole race to which it belongs,” and we

heartily concur with him in that opinion.

It is not a little remarkable that, although this handsome

Aisculus was distributed by Dr. Wallich as long ago as 1828,

and recorded in his well-known ‘ Catalogue’ as Pavia Indica of

Colebrooke’s MS., and as a native of Kamaon (Blinkworth) and

of Sirmore (8. Webs), it was never described nor further noticed

by any author till the appearance of the ‘ Plante Rariores quas

in India Orientali collegit Victor Jacquemont : auctore J. Cam-

bessédes,’ in 1844.

“India borealis” is popularly given for the native country of

our common Horse-chestnut (Asculus Hy pocastanum), but Dr.

Royle assures us that “Its native region Is still unknown ; it

is not enumerated in Dr. Wallich’s catalogue, nor has it ever

been distributed by him. I have never met with it, though

often visiting the northern mountains of India, where, if any-

where, it was likely to be found, and where the nearly allied

Indian Pavia® is so abundant.” The Pavia (or dsculus) Indica,

or Indian Horse-chestnut, which we now figure, that author

further says, “is called by the hill-people Hunour and Pangla,

and is found on mountains, at elevations of from 8000 to 10,000

feet, in Kamaon, Gurhwal, and Sirmore, also near the sources of

the Ganges, and in Kunawur. It is a lofty and not less orna-

mental tree than the common Horse-chestnut, The bulky seed,

containing a large proportion of feecula, though combined with

some bitter principle, is eaten in the Himalayas, as those of the

Horse-chestnut have been in other parts of the world in times of

famine. The bark of the latter, from its astringent properties,

being employed as a tonic and febrifuge, it is worthy of inquiry

whether the Himalayan species of Pavia is possessed of any of

the same properties.”

We owe the specimen here figured to C. J. Fox Bunbury, Esq.,

who transmitted it to us from the family seat at Mildenhall,

Suffolk, in July of last year (1858). It was taken from a tree

raised from seeds sent by his brother, Colonel Bunbury, from

the north of India, sixteen feet high, the circumference of its

stem eight inches; its age from the sowing of the seed seven

years; and it had on it, at this early age, twelve panicles of

flowers. Of the hardiness of the tree in our climate there can

be no question. Two or three years ago the first flowers were

produced, when specimens were also kindly communicated to us

by Sir Henry Edward Bunbury, K.C.B.

Descr. This forms a good-sized éree in its native country,

much branched. The dranches rounded, glabrous. Leaves

ample, opposite, on long foot-stalks. Leaflets seven to nine,

spreading, rather long, all petiolulate, broad-lanceolate, serrated,

subacuminate, dark-green, above subglaucous, beneath firm and

subcoriaceous when dry ; terminal leaflets the largest, almost a foot

long. Flowers numerous, in terminal, thyrsoid, rather Jax panicles

somewhat angular; superior lip 3-toothed, inferior bidentate.

Lips erect (not spreading). Petals five, unequal, oval or obo-

vate, clawed, very downy on the back, spreading but not regu-

larly subsecund ; a fifth petal is often wanting (the lower one),

the colour is white, the two superior and narrow ones having 4

blotch of red and yellow at the base, the lateral ones blush-

coloured there. Stamens five to eight, scarcely longer than the

petals, spreading. Anthers ovate, with a short blunt spur at the

base of each cell. PistiZ : ovary oblong, downy ; style subulate,

downy ; stigma obtuse. |

A handsome plant, frequent in the West India Islands, liable

to some slight variations in the leaves, and in the depth or pale-

ness of colour of the flowers, but not sufficient to justify the

Separation of C. rotundifolia, as was done by Salisbury, or the

C. speciosa by Presl, as distinct species. The C. scandens of Sims

in Bot. Mag., if intended for this plant, is a miserable representa-

Hon, and widely different in habit and in the colour of the flowers,

and in the form of the corolla and- calyx. Our plant succeeds

a cultivated in a basket suspended from the roof of a moist

Desor. A scandent species, but to a moderate extent ; the base

of the stem becoming fruticose in age, the rest is herbaceous,

obtusely quadrangular, downy, as is more or less the whole plant,

rooting occasionally at the joints, branched; dranches opposite.

Leaves opposite, with short stout petioles, about half an inch long ;

ovate or oblong-ovate, thick, fleshy, acute or subobtuse, downy

on both sides, the margin entire or calloso-serrate, penninerved,

dark-green above, paler beneath. Peduncles axillary, longer than

late, erect segments, having at the base on one side.one or two

soft spine-like teeth. Coro/la more than two inches long, dark

flesh-colour, deep-red above, villous; the Je moderately curved

and laterally compressed, tapering towards the base; Jimd of

two very unequal /ips ; upper lip very large, three-lobed ; lateral

lobes spreading, small, oblong ; intermediate one very large, for-

This pretty species, of which seeds were sent by Dr. Thomson

from the Sikkim-Himalaya, belongs to an intricate group of the

genus, including G. discolor, Dathousiana, and penstemonordes,

from all of which it differs in its more slender habit, fewer

almost invariably terminal flowers, and slender tube of the deep

violet-purple corolla; it also approaches very nearly some states

of the variable G. Wallichii (Strobilanthes Wallach, Nees), but

- that plarit has a much more tumid corolla, with a broader tube

and narrower limb. All these and many others of the genus

are well worthy of cultivation, from the beauty and abundance

of their blossoms, which are produced in succession for several

weeks. The G. Thomsoni has been gathered by Drs. Thomson

and Hooker in Garwhal (west of Nepal), in Sikkim, at elevations

of 6-9000 feet, and in the Khasia Mountains, if we are right in

our identification of these specimens, which in a dried state 1s @

matter of great difficulty. :

lax habit. Stems slender, glabrous, a foot or two high, sparingly

branched. Leaves two to three inches long, the lower pairs

From a drawing made by Mr. Holden, of Warrington, at Nut-

grove, Rainhill, Lancashire, where this plant flowered for the

first time in March, 1859. It was discovered and introduced to

England by Mr. Booth, who detected it on the northern slopes

of the Lablung Pass, Bootan, in company with 2. Hookeri, Nutt.,

and like that it promises to be hardy in our climate. Its affinity

is with R. barbatum, and it is remarkable for the nature of the

tomentose clothing of the under side of the leaves. Hach hair

is jointed, stout at the base, rather copiously and dichotomously

branched, as is shown at our Figures | and 2. Mr. Nuttall de-

sires it should bear the name of the late Sir James Edward Smith,

who was the first to call public attention to its ally the Indian

Rhododendron arboreum, now so well known in our gardens.

general aspect of the original 2. arboreum and R. barbatum.

Leaves a good deal clustered about the extremities of the

gins entire and reflexed; above strongly veined, dark-green, —

J Misc. v. 5. p. 228,

This very remarkable plant, which in its habit and foliage

resembles no other of the Natural Order to which it belongs,

was first in 1835 imperfectly noticed by Kunze as a South

African Fern (Zomaria), and was sent by Dr. Stanger from

Natal to N. B. Ward, Esq., and by him given to the Chelsea

Botanic Gardens long after, viz. in 1851. It was first de-

scribed by Mr. Moore, from imperfect specimens, as a “ Zamia-

ike Fern,” or “Fern-like Zamia,” and the opimion exp

that its affinity appears to be rather with Cycadee than Ferns,

which has since proved to be quite correct. In 1854 speci-

mens with cones were exhibited to the Linnean Society by

Mr. Stevens (Proc. Linn. Soc. v. 2. p. 340), and since then

both male and female ones have been produced at Kew, but

unfortunately not in the same year. Of these, a pair of ris

ones, formed in April, 1858, produced perfect ovules, an

withered away; and in the same month of the present year

another plant produced the male cone figured in our Plate.

Our specimens were received from Mr. Plant.

JUNE lst, 1859.

The affinity of Stangeria is very close to Encephalartos, nor is

there any structural difference of importance between the fruc-

tifications of these genera; in habit and foliage, on the other

hand, they widely differ, and most conspicuously in the short,

turnip-like stem of Stangeria, that bears no persistent bases of

the fallen leaves, in its few terminal leaves, and in the Fern-like

venation of its pinne. This difference between the venation of

the pinnee of Hncephalartos and Stangeria is very analogous to

that between the species of Podocarpus with Dammara-like

foliage, and those whose leaves have a midrib.

Mr. Smith, in his paper.on Sfangeria, after showing that.

Stangeria paradoxa was first referred to Lomaria coriacea of

Schrader by Kunze, in the Linnea, and that he subsequently

made a new species of it as Z. eriopus, also in the Linnea, gives

some valuable remarks on the venation of the frond of this and

other Cycadee. I have hitherto had no opportunity of examin-

ing a caudex of this singular plant, but I find the vascular bundles

_ of the leaves to be formed of annular ducts surrounded by elon-

gated cells, and also that there is a thick layer of wood-cells

immediately below the cuticle of the stipes. The cuticle of the

under surface of the pinne abounds in large stomata, and the

cuticular cell-walls are much undulated. Globular white concre-

tions with granulated surfaces, occur abundantly in the cellular

tissue of the stipes, and are probably composed of oxalate of lime.

Desor. Caudew about a foot long, tapering to the base, and

terminating in a few roots; contracted at the apex, and there

giving off three to six leaves. Bracts few, imbricating, broadly

ovate, blunt, woolly. Leaves spreading, two feet long by one

broad, glabrous except at the woolly base of the petiole. Leaflets

about twelve pair, opposite, the lower petiolulate, the upper sessile,

with a broad, adnate, decurrent base, smooth, glossy, bright-

green; margin serrated beyond the middle, slightly thickened,

plnnately veined. Veins reaching the margin, all free. J/ale cone

on a long, terete peduncle, six inches long by one and a quarter

broad, blunt; apices of scales woolly, trapeziform. Azthers

very numerous, yellow. Female cones similar to the males, but

much shorter, about two to three inches long. Scales similar to

the males externally, but shorter, more concave, broadly ovate

when looked at on the inside, with two minute deep cavities on

either side of the insertion, in each of which a small, broadly

obovoid ovule is wholly sunk, its apex only protruding. Ovule

with a single fleshy coat and contracted micropyle. J. D. H.

A species entirely new, as far as can be learned from the very

imperfect descriptions of the individuals of the genus Agave in

Horticultural Society of London, who received it from Texas.

Its nearest affinity is probably with Agave saponaria of Dr.

This is another of the beautiful and novel forms of Rhodo-

dendron introduced by the venerable Nuttall from the mountains

of Bhotan and Assam, and flowered by himself at Nutgrove, in |

Cheshire. Tt differs from Rhododendron Kendrickii (of which a

Plate will soon appear), in the glabrous ovary and large calyx ; .

from R. arboreuvm in the colour of the under surface of the leaf, —

the slender nerves, and larger calyx; and from &. eas

which is perhaps its nearest ally, in the absence of seta on

petiole, and small calyx. Mr. Nuttall remarks that it grew on —

the Oola Mountains of Bhotan with 2. eimium, and that it is —

named in honour of Mr. Henry Shepherd, of the Liverpool

_ Garden. Our engraving was made from a drawing

This lovely and rare Orchid has hitherto been found by one

botanist only, the late Mr. Griffith, who, according to Dr. Lind-

ley’s notes on the Orchidology of India, discovered it at Myrung,

on the Khasia mountains of East Bengal, where it grows at an

elevation of about 5-6000 feet. Fine plants were imported by

Messrs. Loddiges, probably from the Calcutta Botanic Gardens,

from which Dr. Lindley described the species in 1847. ‘The

specimen figured flowered in the Royal Gardens, Kew, in April

of the present year, and its scent, which is scarcely so sweet as

is usually described, slightly resembled that of starch.

_ For this magnificent acquisition to our hardy shrubs we are

indebted to Messrs. Veitch and Sons, of the Exeter and Chelsea

Nurseries, who introduced it from California through Mr. William |

Lobb. Though closely allied.to and in many respects so similar

to Ceanothus floribundus (Tab. 4806), C. Lobbianus (Tab. 4811),

and C. papillosus (Vab. 4815), it is abundantly distinguished

from them by the characters of its foliage ; and, beautiful as they

are, it far surpasses them all in the abundance of its bright

mazarine-blue flowers, and the glossy, almost varnished surface

of its deep evergreen foliage. The specimen sent us by Mr.

Veitch was fully three feet long, and the profusion of flowers

was so great that the leaves were almost concealed throughout

the whole length of every twig. To distinguish 1t accurately,

attention must be paid to the perfectly glabrous branchlets, upper

surface of the leaf, petiole, pedicel, and calyx, to the glossmess

of that surface, to the venation beneath, which consists, besides

the midrib, of about four, very stout, straight, parallel nerves,

_ given off at an acute angle to the midrib on each side ; as also to

the pubescence of the minute areoles between the venules, which

under the microscope is found to consist of minute, converging,

fimbriz or short hairs. 1t does not exist in our herbaria from

any North-American or European collectors.

Dzscr. A ramous shrub, with terete, glabrous, green, straight

branches, and bright-green, small, glossy leaves of very uniform

a deciduous gland. Heads of flowers one to three inches long,

forming when in bud broadly ovoid cones at the ends of the

branchlets, covered with imbricating, silky scales. Rachis stout,

villous. Peduncles slender. Calyzx-lobes erect or incurved, tri-

Flore pleno. (Tas. Nosrr. 5128.)

My first knowledge of this really handsome plant was from

specimens which flowered at Sion House in 1845, raised from

seeds sent to his Grace the late Duke of Northumberland by

Dr. Wallich, but from what country is not known. The deter-

mination of the species of Datura is attended with great diffi-

culty, as all will acknowledge who have made the attempt,

partly owing to very imperfect specimens in our herbaria, and

more so from the very variable character of the individuals, their

change of colour, and their disposition to become double ; and I

confess myself to have been fairly puzzled with this, and I put

the drawing of it aside for future consideration. =

In May of the present year my attention was again directed .

the subject by a recent specimen of the same plant, sent by the

Messrs, Henderson, of the Nursery, Pine-apple Place, ee

Road, who received secds of it from Mr. Francis, the curator 0

the Adelaide Botanic Gardens, South Australia, with the fol-

lowing remarks :—* A species of double yellow Datura, very

Plentiful in these parts, sweet-scented, and flowering all the

summer, of a low spreading habit, producing its flowers ee

to eight months throughout the twelve. This will be a use

plant to you in England; planted in the open borders in June,

you may expect it to flower finely during the months of August,

September, and October. Here it stands the winter, being al-

most deciduous. I never saw it when in England. It is worth

your growing, being a free bloomer.”’ There is no reason what-

ever for supposing the species to be a native of Australia: on

the contrary, it is more likely seeds were sent from Europe to

Adelaide, where it would naturally be more hardy than with us.

Our plant is evidently arborescent, and of the Brugmansia

group. It cannot be the true D. arborea of Linneus, which ’

has quite entire as well as downy leaves; nor the D. ardorea of

our gardens (D. Gardueri, Hook. in Bot. Mag. sub t. 4252);

nor the D. arborea of Ruiz and Pavon, t. 128, which is more

like our D. cornigera, Bot. Mag. t. 4252, but is widely different.

The leaves of D. chlorantha accord in shape with our D. corni-

gera; but they are quite glabrous, and the calyx is widely dif-

ferent, as is the colour of the corolla. These differences are

best seen by a reference to the respective figures. It need

hardly be said that it has nothing to do with the D. sanguinea

of Ruiz and Pavon.

Amongst the many new and beautiful species of Rhododen-

Surpass this in the gorgeous colouring of flower. It was collected

by Mr. Nuttall’s nephew, Mr. Booth, at 7000 feet elevation, ac-

companying #. dgeworthii, in the region of Pines and Yews,

where it forms lofty thickets after the manner of 2. Pontecum,

through which he says the traveller finds dark and difficult paths.

It had, however, been previously discovered by Mr. Griffith, and is

the n. 2235 of his Bhotan collection. The original specimens have

considerably narrower leaves than those here figured, and they

_ are perfectly glabrous beneath. We are indebted to the same

accomplished artist, Mr. Holden, of Warrington, for this draw-

— ing, as for those of R. Shepherdii and Windsorii. The plant

Paxton’s representation of this rare Dendrobium, exhibits the

flowers twice the size of ours, and the peduncles one- to two-

_ flowered, coming out of old withered pseudobulbs; but Dr.

Lindley’s notes which accompany it, throw suspicion on that

figure, which is probably made up from imperfect dried speci-

mens ; for he says, “If it really forms racemes (as stated by oe i

Lobb), it will have to be removed from the section Ludendro-

bium, to Stachyobium.” It is a native of Attran River, in Moul-

consequently,” write Humboldt and Bonpland, who gave to this

_ hew genus the name of Cheirostemon, “ been transported by the

Indians of Toluca from its native woods, and that, too, long before

the conquest of America, since it is recorded in the writings of

authors, previous to the celebrated expedition to Mexico, under

the Indian name Macpalxochiquauhitl, signifying Hand-flower-

tree. It was, however, never botanically noticed till 1795, and

then by Professor Cervantes. So great an object of curiosity

was this with all the inhabitants of New Spain, that the flowers

were gathered with avidity by the Indians even before their full

expansion, and thus seeds were not allowed to ripen. Cuttings

were transported to gardens in Mexico by Sesse and Mocifio;

and at length their labours were rewarded by one, and only one,

succeeding.”

Humboldt and Bonpland brought seeds to Paris on their re-

turn from Mexico, but none of them germinated. More perfect

seeds were afterwards readily obtained. Humboldt, in 1811,

speaks of its being in collections at Paris and Montpellier ; and

not long after Mr. Lambert seems to have introduced it to English

gardens. A fine plant had been long in cultivation at Kew, where

it has attained a height of twenty-three feet, but never showed

any disposition to flower. Happily Charles Dorrien, Esq., of Ash-

ean, has been more successful, and fine and perfect flowers were

produced in his garden in the spring of 1859, from which, by

the kindness of this gentleman, our figures have been made.

€ Specimens arrived in the most perfect state possible, and

Were accompanied by the following notes :—‘“ The tree is ever-

green, but loses part of its leaves in winter, so the branches are

bare in the lower parts. It seems to like a temperature of about

50° or 55° in winter. The first blossoms are (May 27th, 1859)

gone off, but there are now four more expanding. ‘The flowers

secrete (in the nectaries at the base within) a quantity of liquid

like sugar-and-water, tasting and smelling like toast-and-water.

Each blossom continues about a fortnight in perfection before it

begins to fade. The plant propagates easily by cuttings.”

Descr. Bonpland, in his ful] description, gives the height of

the trunk of this tree at fifteen feet; yet in his notice of the

plant flowering in the city of Mexico, states it at thirty feet.

Our own individual is twenty-three feet, with a diameter of six

inches, bearing a rather spreading crown of branches, clothe

with handsome foliage, which is partially deciduous in the win-

ter. Leaves very much confined to the extremity of the branches,

as in Many species of Sterculia, which the tree much resembles

in habit, and the portion of the branches bearing the foliage 1

clothed with rusty-brown tomentum ; the rest of the branches

glabrous, with brown, smooth bark, or only scarred from the

fallen leaves. The form of the /eaves is cordate, rather obtuse,

of a firm subcoriaceous texture, about six inches long by five

broad, having a deep and acute sinus at the base; the margin

is three- to seven-lobed, lower lobes very obtuse, entire, not ser-

rated, as represented by Bonpland, five- to seven-nerved, and

these principal nerves are united by transverse reticulated ones,

prominent beneath ; young leaves tomentose on both sides, older

ones nearly glabrous above, densely tomentose beneath ; the éo-

mentum rich, ferruginous, composed of stellated hairs, as shown

at Fig. 5. The youngest leaves have small recurved stipules.

Petioles from three to four inches long. owers large, solitary,

lateral, from among the crowded terminal leaves, and opposite

to the insertion of a petiole. Peduncle an inch or an inch and a

half long, obtusely triangular, very stout, curved, single-flowered,

bearing two, ovate, acuminate, deciduous bracts, of which one

is appressed to the flower. Flower four inches long, including

the stamens. Perianth single, calycine, two inches long, and

quite as much broad, thick, firm, coriaceous, downy, of a rusty-

red colour, brighter and glabrous and glossy and somewhat

wrinkled within, cup-shaped, deeply (two-thirds of the way down)

divided into five, large, acute, erect lobes, which have the mar-

gins a little reflexed, and a strong dorsal keel, which terminates

below in five gibbosities or spurs, forming internally as many

deep nectariferous cavities, of a bright yellow colour. Stamens

five, monadelphous, bright-red, nearly four inches long, one-third

of them below uniting into a tubular column, which at the spread-

ing base combines with the perianth, exhibiting five, spreading,

yellowish rays or lobes, alternating with the nectariferous cavi-

ties ; the rest of the stamens are free, and spread ina fan-shaped

manner, like the fingers of the hand (whence the name Cherro-

stemon), or rather, like birds’ claws, and like them curved to one

side, cylindrical, very much acuminated. On the under side of

these five filaments (and externally, with regard to the axis of

the flower) are two, long, linear, yellow anther-cells, charged with

copious bright-yellow pollen. Ovary quite concealed within the

base of the monadelphous stamens, five-lobed, woolly, tapering

into a bright-red, clavate style, shorter than the stamens, an

bending towards them: this tapers into the acute stigma. The

fruit we have only seen from dried native specimens. That here

figured (nat. size) is taken from one in the Museum of the Royal

Gardens of Kew: for its structure, see the generic character.

This very lovely Boragineous plant, which cannot fail to call

to mind the favourite Forget-me-nots of Europe, is an inhabitant

of Chatham Islands, off New Zealand, S. Lat. 44°, whence it

was introduced to Europe through the medium of Mr. Watson,

of St. Alban’s, by whom a living flowering plant was exhibited

at a meeting of the Horticultural Society of London, in March,

1858, and attracted much attention. With the inflorescence of

a Myosotis, it has a fruit which, in the state of ovary,. induced

Dr. Hooker to refer the plant to Cynoglossum : but the fruit is

quite different from the characters of both, approaching Ompha-

‘odes in the winged achenia or nuts, yet differmg in the nature

of that wing, not being in any way introflexed, nor are the nuts

attached to the style, as in that genus. Its foliage is quite un-

like any species of those genera, and we think it may justly be: -

considered a new genus, ranking very near the Forget-me-nots.

The whole stock of this choice plant is (we believe) in the posses-

sion of Mr. Standish, who sent the plant here figured to us m

The importance of the noble Palm-house at Kew, 1s now —

beginning to be felt by the blossoming of many rare Palms,

which have never before produced flowers im any European

collections. Although one of the less lofty kinds of the princes

of the Vegetable Kingdom, the present is an extremely elegant

species, native of the Northern and Middle Islands of New Zea-

land (where the young inflorescence is eaten), and of peculiar

interest, as being one of the most southern representatives of its

Natural Order, occurring as far as latitude 38° 22 south; whereas

“38° is the limit of Palms in Australia, latitude 38° in South

America, and latitude 30° in Africa.” i

As Dr. Hooker has had the opportunity of seeing and study-

ing this plant in its native islands, and as he has recently pub-

lished a good description, together witha figure of the inflorescence

and fruit, we cannot do better than offer the following extracts

from his ‘Flora of New Zealand.’ Its flowerimg season with

us has been in the winter months. Mr. Allan Cunningham has

applied to this Palm, Endlicher’s description, drawn up from

SEPTEMBER lst, 1859.

Ferdinand Bauer’s drawing of Norfolk Island specimens (which

have been considered by some as the same species); but this

does not agree with the Zew Zealand plant in the shape of the

drupe, said to be “ globose” in Norfolk Island. Mr. J. Smith,

of the Royal Gardens, Kew, has both of them in cultivation,

and has pointed out a very considerable difference in habit, and

in the breadth of the pinnules, those from Norfolk Island being

twice as broad; but there is great variation in this respect in

both species. Von Martius also separates them, but gives

Forster's name to the Norfolk Island plant, whereas Forster's

drawing is from the New Zealand one only, to which the name

of sapida must remain attached, whilst that of Baueri may be

given to the Norfolk Island species, if it prove really distinct.

The genus Areca, our species of which yields the well-known

Betel-nut (Areca Catechu), is found in Asia and its islands; but

the group to which 4. sapida belongs, and which has a one-

celled ovary, is supposed to be confined to New Zealand, Nor-

folk Island, and the Malay Archipelago. Mr. Brown distin-

guishes the Australian nearly allied Palm by the name of Sea-

Jorthia (see our Tab. 4961): it resembles the New Zealand Plant,

but differs from it in having numerous stamens and ruminated

albumen.

_Duscr. 4. sapida is a small Palm.’ Trunk six to twelve feet

high (Allan Cunningham says twenty feet), six to eight inches in

diameter. Leaves pinnate, four to six feet long; pinnules very

narrow, linear-lanceolate, margins replicate ; zerves and costa, and

especially the petiole, covered with minute lepidote scales. Spadix

much branched, densely flowered, eighteen to twenty-four inches

long, enclosed in a double, boat-shaped spatha. Flowers very

numerous, of a pale-pinkish colour, ma/es and Semales intermixed,

one of the former being generally placed between two of the

latter, all sessile. Male perianth six-cleft, or of six, ovate, acu-

minate pieces, in two rows, outer one smaller. Stamens six,

surrounding the rudiment of an ovary. Female perianth also of

six broadly ovate leaflets, rolled round one another, and enclosing

a one-celled ovarium, with three sessile stigmas and a pendulous

ovule on one side of the cavity. Fruit an ovoid drupe, half an

inch long, with a fibrous outer coat; the membranous éesta

thickened on one side down the raphe; albumen horny, the surface

not ruminated. Hmdbryo small, in the base of the albumen. J.D..

Professor Kunth, with great propriety, separated the genus

the genus Calla of Linnwus, peculiar to Europe tener r

to an entire absence of colouring matter. As a species, this is

perfectly distinct from 2. Africana, in the different form and in

the almost coriaceous texture of the leaves of the latter, which

are moreover abundantly marked with pellucid veins, and they

have a pellucid edge; nothing of the kind exists in our present

species. The spatha, above the involute portion, is much nar-

rower, and never reflexed ; the interior base is coloured, and the

spadix is much shorter than in 2. Africana. This will probably

prove as hardy as the latter mentioned. The other Richardia,

from Messrs. Veitch, we shall notice on a future occasion.

that of the well-known &. Africana, that it will suffice to notice

the distinguishing marks from that species. The,foliage is of a

much thinner texture, flaccid, and submembranaceous, paler in

colour, truly hastate (not sagittate) in form, destitute of pellucid

veins and margin; the petioles are more slender. The spatha

is much less expanded and less broad above-the convolute por-

tion, and this portion is nearly erect, not recurved; the inside

is purple at the.base. The spadixv is much shorter, and espe-

cially the staminiferous portion, in relation to the pistilliferous

base. The ovaries and young fruits have their cells varying

from one to five.

It fell to the lot of the distinguished German traveller and.

botanist Dr, Pceppig, to dedicate a genus of plants to om

countryman John Evelyn, an eminent patriot of the pte oe

century, and author of ‘Sylva; or a Discourse of Forest rors,

and the Propagation of Timber in His Majesty's Dominions ;° to

Which is annexed ‘Pomona; or an Appendix concerning aT

Trees, ag relating to Cider; and as a sequel to this wor :

afterwards published his ‘Terra; a Philosophical ee we 0

Earth, relating to the Culture and Improvement of it for ege-

tation, and the Propagation of Plants.’ The first of these works

alone would richly entitle him to this honour. _ - .

The species which were selected, as belonging to this new

genus, are five in number, all discovered by Dr. Poeppig —

his Peruvian travels. Dr. Lindley, however, ascertained that oe

first known species referrible to this genus was derived from t :

M‘Fadyen, and by him communicated to our Herbarium. It is

at once distinguished by the copious black rigid hairs investing

the stem and leaves and ovary and even the calyx. The bracts

are remarkable for their purple colour, while the flowers are

bright-yellow. Plants communicated by Mr. Van Houtte, flow-.

Drscr. An epiphyte, attaching itself to the trunks and

branches of trees in its native forests. Stem about a foot high,

erect, slender, terete, about as thick as crow’s-quill, hispid, as is

all the foliage, and more or less the bracts and calyx, with rigid,

black, short, moderately patent hairs. Leaves distant, on long,

sheathing bases, lanceolate, rigid, very long, and gradually and

finely acuminate ; with two teeth below the spinulose apex, six

to eight inches long, more than an inch wide, plicato-nervose,

harsh and rigid, gradually smaller and more approximate up-

wards, rather suddenly passing into coloured bracts. Spike

elongato-capitate, very compact, formed of numerous, erecto-

patent, purple, lanceolato-acuminate, imbricated, striated dracts,

longer than the flowers. Flowers bright-yellow, with a short,

purplish, inferior, twisted ovary. - Calyz of three ovato-lanceolate,

suddenly acuminate, nearly erect sepals. Petals shorter than

the lip, as are the oblong, obtuse, nearly erect petals. Lip large,

erect, three-lobed : lateral lobes short, incurved; terminal one

large, subrotund, deeply and beautifully fringed: the disc at the

base white, furnished with two large glands, which correspond

with two obtuse spurs or gibbosities on the under side of the base

of the lip. Column shorter than the lip, erect, nearly terete, white.

Anther dark-purple, sunk into the two-toothed clinandrium. -Pod-

This very singular plant is a native of California, and was

first detected by Col. Fremont at the Forks of the Nozah river,

in the foot-hills of the Sierra Nevada of northern California,

in flower and fruit in the month of May. From those native

specimens it was constituted a new genus by the excellent Dr.

Torrey, and dedicated to “Mr. Isaac Sprague, of Cambridge,

Massachusetts, so well known as a botanical draughtsman, and

especially for the admirable illustrations of the Genera of the

Plants of the United States by himself and Dr. Asa Gray. It

has since been found by other and by English collectors 1n Cali-

fornia, and it has been introduced alive to the gardens of Messrs.

Veitch, at Exeter and Chelsea, through Mr. William Lobb, and to

those gentlemen we are indebted for the beautiful specimens here

figured. It was exhibited in July of this year at a meeting of

the Horticultural Society, and «eommended as a very elegant

dwarf-flowering species, of novel character, well adapted for rock-

gee and the margins of flower-borders, having proved quite

ardy in Mr. Veitch’s nursery.”

above specific character and following remarks. |

_ “This resembles Lelia flava (Bot. Register, 1842, t. 62), but

is far larger and handsomer. It most especially differs in the

undulated sepals and petals being leathery and very convex, In

consequence of their sides being rolled backwards, and in the

form of the lip, which when spread flat is nearly quadrate, the —

front side, which is widest, being divided into three shallow lobes —

of equal depth, while the lip of Zelia flava is deeply three-lobed, _

the middle lobe being crisp and much longer than the side ones. — oe

oreover, in the plant now before me, the lip has no trace OL

raised veins, while, on the contrary, in Lelia flava, it has four in

es middle very conspicuously raised above the general level.

One of the tropical stoves at Kew has been rendered very at-

tractive for some years past by the introduction of various Cu-

curbitaceous plants, trained under the rafters and the lights. It

is a family of plants that have been too much neglected, for they

present no small degree of beauty in their flowers, and their

fruits are remarkable in their size or form or colour, and often

will flower and

their utility. Even in the open air many species

ripen their fruit in the open ground. The present plant is of

recent introduction ; the ripe, curiously compressed and embossed _

seeds, accompanied by a drawing, were sent to us from Moul-

mein by the Rev. C. 8. P. Parish, and prove to be those of the

Momordica mixta of Roxburgh; and this is considered identical

with the Muricia. Cochinchinensis of Loureiro: if so, it is exe-

crably described, but is thence shown to be a native of China

ever been published, yet the flowers are both large and hand-

some. Unfortunately our plants have produced only male

flowers: these quite suffice to form a judgment of the species,

especially in conjunction with an outline representation of the —

fruit, copied from the unpublished drawings of Roxburgh, in

the museum of the India House. The plant flowered with us

in July.

Descr. Stems climbing, rather slender, angular. Zeaves on

long, grooved petioles, bearing conspicuous Peziza-shaped glands,

varying in size, cordate, three- to five-palmato-lobate, the seg-

ments sinuato-dentate. Opposite the petioles are simple fen-

drils. Peduncles \ong, single -flowered, bearing a two-lobed

pilose bract beneath the blossom. FV/ower (male) very large,

full four inches in diameter. Calyx deeply cut into five, ovato-

lanceolate lobes, striated with black. Corolla patenti-campanu-

late, of five, rotundato-trapezoid, acute pefa/s, copiously veined,

prominently so beneath, subundulate, pale straw-coloured ex-

ternally, villous within on the disc: the three inner petals black-

purple at the base. Stamens as in the genus, with very long

sinuous anther-cells. Fruit large, oval-rotundate, red, muricated,

acute, three-celled, containing many large seeds.

As Victoria regia is justly considered the Queen of Water-

lilies, so the plant here represented may with equal justice be

called the Prince of Rhododendrons. Yet our figure, though on

a quarto size, does no justice to the plant itself, |

the Rhododendron House at Kew in May of the present year;

and of which a drawing of the flowering portion, on impen

folio, is now before us. The height was nine feet. The principal

branch was terminated by a corymb of ten or twelve flowers,

the cluster measuring fifteen inches across: the corollas white,

yellow in the centre, having measured six inches across, with a

tinge of blush on the lobes; and the bud, just before erie

is of the same length. The leaves have their charms too: the

largest of them a foot long, including the short thick Lap 8 rm

much puckered on the superior surface, that is swollen or b ee

in the areoles of the network, and these reflect a strong lig @

first bursts forth. Such a Rhododendron well merits the name of

the late Mr. Nuttall, given to it by its discoverer, Mr. Booth;

and we know that but a little before his lamented death, one

of the last sources of pleasure he derived from the vegetable

creation, which he had so long and so successfully studied, was

the information of his namesake having for the first time flow-

ered (at Kew), and the sight of the large drawing above referred

to. The species was discovered by Mr. Booth, in the “ Duphla

~ Hills, at Meré Patao, about Seram’s village, on the banks of the

Papoo, Bhotan, growing in swampy grounds, among Yews and

Oaks, sometimes epiphytically on trees, and at an elevation of

from four to five thousand feet above the sea-level.” We have

seen a drawing of a specimen in the possession of Mr. Standish,

which flowered on the Continent ; and Lady Dorothy Nevill in-

forms us she has a plant showing flower at this time (October,

1859).

Bryopuy.iuo proliferum. Bowie, MS.

If the two genera, Kalanchoe, Adans., and Bryophyllum, Salisb.,

are to be retained, the present singular plant belongs to the

latter genus, indicated by the monophyllous inflated calyx; and

the species, though possessed of little beauty to recommend it,

is nevertheless very peculiar, and deserving of place in a green-

house to those who cultivate succulent plants. ‘The stout, and

at the base almost woody stems, attain, with us, a height of

10-12 feet, and when the copious corymbs of flowers appear,

they are disfigured by the quantity of proliferous shoots spring-

ing from the bases of the pedicels ; whereas, as 18 well known,

a similar power of reproduction exists in the crenatures of the

leaves of Bryophyllum calycinum, especially when the leaves

come in contact with the soil. It is a native of Madagascar, but

certainly neither under Bryophyllum nor under Kalanchoe is there

anything described like it. There is a Kalanchoe Delugoensis, —

as its specific name implies, of Delagoa Bay, a good deal to the |

east of Natal, but all that is said of it is (Eckl. et Zeyh. Enum.

cel. Commodore Owen ad Delagoa Bay legit, et nobiscum com-

Cape of Good Hope, and which he received as dried specimens

for the herbarium, by Mr. Bowie. The species requires a warm

and dry house for its successful cultivation.

Drsor. Stem ten to twelve feet high, moderately branched, -

rounded and terete, and almost woody below; the branches

acutely tetragonal, very succulent, as is the whole plant. Leaves

a foot to a foot and a half long, opposite, impari-pinnate, with

about five opposite pairs of leaflets, which are sessile, subde-

current, oblong-lanceolate, obtuse, crenate. Rachis very thick,

deeply furrowed in front. nflorescence terminal, in compound,

pedunculated, proliferous cymes: sometimes all are proliferous,

at other times the pedicels bear drooping flowers, one and a

half inch long. Calye large, inflated, bluntly tetragonal, with

NOVEMBER Ist, 1859.

The genus Dissotis, chiefly differing from Osbeckia by the very

long connectivum and dissimilar anthers, was established by.

Mr. Bentham on a Sierra Leone plant, the Osbeckia grandifiora,

Sm., and the Osbeckia Senegambiensis ? of Guill. and Perott., of

which a specimen in my herbarium from Heudelot, Mr. Bentham

observes, is apparently the same. Our present species is very

different from that in the form of the leaves and of the scales, or

tubercles (as they may rather be called in this instance), of the

tube of the calyx; the whole plant, too, is much more villous,

and the root is in no way tuberous.

Descr. Root subrepent, perennial ?, sending out copious black

fibres. Stem one to two feet and more high, herbaceous, clothed

as is the foliage, with long, villous, spreading hairs, in the native

dried specimens having a purplish cast upon them, obtusely four-

angular: dranches copious, more acutely four-angled. Leaves

two and a half to three and a half inches long, shortly petiolate,

lanceolate, three- to five-nerved, somewhat rigid, quite entire.

Flowers solitary, terminal, smaller than in Dissotis grandiftora.

Petals purple-rose. Oalye short, urceolate, clothed with tuber-

culiform, clavate, spreading scales, each terminated with a pencil

of long purplish hairs or sete; dimé of five, spreading segments,

each with a gland at the point. Disc of the ovary conical, five-

angled, with a few hairs on the angles, and a long tuft of hairs

surrounding the style. Stamens ten, alternately small, the lesser

ones with a very short connectivum, the larger ones with a very

long curved one, bearing the large, purple, falcate anther, which

opens with one pore at its summit.

This is one of the many interesting plants which our Gardens

owe to Mr. Fortune’s successful voyages to China. ‘That active

traveller considered it to be a variety of the Waratah Camellia

group; but Dr. Seemann, with more justice, considers it to be a

variety of Camellia Sasanqua. “ Hitherto,” writes Dr. Seemann,

in an Addendum to his elaborate synopsis of the genera and

species of Camellia and Thea, “ the Waratah form of Camella

was only known to occur in C. Japonica ; and the yellow colour

is certainly quite a new feature in this genus, deserving the

greatest attention of Horticulturists. — That C. Sasanqua has a

tendency to assume a yellow tinge 1s evident even from the

single-flowered state, as will be seen in the figure in the Bot.

rose-colour peculiar to the Yellow Camellia.

This is one of many specimens of rare and curious species of

plants with which the excellent Bourgeau, prince of botanical

collectors, has enriched the herbaria of scientific botanists. It

was found by him on his last voyage to that interesting group

of islands at Lancerotte. Seeds which we likewise received

from him have been raised, and our figure is taken from one

of the plants so reared, in a cool greenhouse, in August, 1859...

M. Boissier places it next to 8. puberula, Webb (see Bot. Mag.

Tab. 3701): the leaves indeed appear to be very distinct, but

they are described as being very variable ; the branches are

more winged: but I do not find the difference the size of the

flowers mentioned by Boissier.

De Candolle (excluding Acantholimon, Boiss., A2 species, Gonio-

limon, Boiss., 7 species, Armeria, Willd., 52 species, and some

distinctions are very finely drawn of many of them, and the per-

manency of some may be questioned.

Descr. This is in many respects so closely allied to the S.

puberula, Webb, above noticed, that we may sum the distin-

guishing characters in few words. S. Bourgiei has the stem

and branches more winged, and leaves so waved and lobed in

the lower half as almost to constitute a lyrate leaf.

large flowers, to be well calculated for a bedding-out plant. The

calyces, as well as the flowers, partake largely of the yellow co-

lour, and these calyces are larger in proportion than the corollas.

continued in bloom during the two succeeding months. In the

present unsettled condition of the genera of Acanthacee we have

been obliged to refer it provisionally to the large genus Diptera-

canthus, as the only one with the characters of which it at all

agrees; at the same time we have little doubt but that it is

congeneric or very closely allied to the Stephanophysum Bavkiet.

of tropical Africa (Tas. Nostr. 5111), a plant which, though

agreeing in many respects with the technical characters of that

genus, differs (according to Pohl’s figures of the Stephanophysum)

- conspicuously in habit, in the stigma not being equally bilamel-

late, and in the whole form and structure of the capsule, and in

wanting the bifurcate retinaculum of the seed. It 1s a most de-

sirable new stove-plant. :
