67 - XANTHOCHYMUS DULGIS. 
DESCRIPTION. 
Trunk quite straight to the top of the tree. Bark smooth, olive- 
coloured. Branches and branchlets opposite, expanding, the 
latter grooved and keeled: height of trees, eight years old, 
about ten feet. 
Leaves opposite, short-petioled, oblong, entire, often pointed ; 
texture hard; bothsurfaces polished ; length about sixinches, 
and from two to three broad. 
Petioles short, transversely wrinkled ; at the base, on the insidea 
fleshy ligule, or protuberance, which is, I believe, common 
to the whole of this order (Guttifere). 
Stipules none. 
Flowers in small fascicles from the axils of one or two years old 
branchlets, peduncled, of a middling size, nearly globular, 
greenish white, inodorous. 
Calyx of four, five, or six unequal, round concave, permanent 
leaflets. 
Petals five, round, sessile, concave, greatly larger than the calyx, 
and just as long as the stamina, contracted into a globe, with 
a small opening at the apex when most expanded. 
Nectary in the male, a truncated, porous, yellow body, with five 
lobes projecting between the insertion of the five filaments. 
In the hermaphrodite, five, yellow, porous glands, alternate 
with the filaments, round the base of the germ. 
Filaments in both five, incurved, broad, flat bodies, divided at the 
apex into six, seven or eight short portions, each of which 
supports a twin anther. 
Germ in the male none ; in the hermaphrodite ovate, smooth, 5-celled, 
with one ovule in each attached to the middle of the axis. 
Stigma 5-lobed. 
Berry size of an apple, from round to oval, obtuse, smooth, bright 
yellow when ripe, fleshy; /esh, or pulp in quantity, yellow, 
and rather sweet, one-celled; what formed the partitions in 
the germ, was the aril of the seed in its early stage. 
Aril: a large portion of the pulp, of rather a softer consistence, 
Style scarce any. 
somewhat darker colour, and pleasanter taste, appertains to 
each seed ; which separates spontaneously, with its seed, from 
each other, and from the exterior, thick, fleshy covering, 
when the fruit is over ripe. This is the only edible part in 
the common Mangosteen, and some other species of Garcinia, 
and in this genus the most palatable part. 
Seeds from one to five, oblong, rather pointed, at the base on the 
inside a large, oblong, lighter-coloured space, marks the 
attachment. Integument single, reticulated with lighter-co- 
loured veins, on a dark cinnamon-coloured ground. 
Albumen conform to the seed, of a hard, fleshy texture. 
Embryo simple, very obscure until vegetation begins, soon after 
the seed is put in the ground, a small root issues from the 
lower end, and from the apex a scaly plumula, which soon 
sends forth from its base the permanent, quick growing root, 
while the small inferior one scarce increases in size ; running 
between these, nearly through the centre of the seed, by nice 
dissection, and a good lens, the appearance of a slender 
cylindrical body may be traced. 
embryo, and if any one can be called simple, certainly this 
may. After vegetation has advanced a little, this mark be- 
comes more conspicuous, as in the vertical section of the 
seed, which had been a month in the ground. 
This I consider the real

Xanthochymus prctorius, and three species of Garcinia, which I

have examined, have exactly the same conformation, and vegetate 
in the same manner. Are they not monocotyledonous ? 
The trees in the Botanic Garden are but small, being only eight 
years old, but very handsome, and the fruit palatable. 
271. AERIDES MULTIFLORUM. 
Parasitic, caulescent. Leaves bifariously imbricated, linear, 
emarginate, with hooked acumen. Racemes axillary, longer than 
the leaves, simple, or ramous. Lip with broad-cordate, entire 
lamina, and short obtuse horn, projecting under it. Capsules 
clavate, 3-sided. 
OBSERVATIONS. 
A large beautiful species, with many, long, closely imbricated, 
hard glossy leaves, and copious very long, suberect, often com- 
pound racemes, of numerous, pretty large, pale-rosy flowers: is 
found on trees, growing on the Garrow hills in the vicinity of 
Silhet, where, with most plants of the order, it blossoms during 
the months of April and May. 
272. ARUM CAMPANULATUM. 
Stemless. Leavesdecompound. Flowers sessile with respect to 
the surface of the ground, and appear when the plant is destitute 
of leaves. Spathe length of the spadix, campanulate, with curled 
margins. No nectary. Club broad ovate-lobate. Anthers 2-celled.

DESCRIPTION. 
Root perennial, tuberous, roundish, covered with a dark brown 
skin, frequently, when in a good soil, as large as a child’s 
head. From various parts of the chief root there issue 
smaller tuberosities which are employed as offsets to culti- 
vate the plant by. 
Leaves radical, for the most part only one or two, thrice bifid, 
divisions outwardly pinnatified, segments obliquely-oblong, 
pointed, smooth, size, very unequal, the exterior being always 
greatly longer than the inferior; the whole leaf is from one 
to three feet each way. 
Petioles round, tapering, clouded with darker-coloured green, pretty 
smooth, about as long as the leaves. 
Spathes very large, leathery, campanulate, border-curled, smooth 
on both sides ; outside near the base pale green ; middle part 
deeper green; and towards the margin greenish purple,
