57 . HEYNEA TRIJUGA. 
Nectarium sub-cylindric, shorter than the petals, half ten-cleft ; 
divisions alternately a little shorter, and bifid. 
Filaments scarce any. Anthers 10, ovate, $-lobed, crowned with 
an obtuse point, attached to the inside of the divisions of the 
nectary. 
Germ superior, immersed in a large fleshy ring, two-celled, with 
two ovula in each cell, attached to the middle of the partition. 
Style short. Stigma large, nearly round, with two-toothed 
apex, which is rather within the mouth of the nectary. 
Capsule round, size of a small cherry, fleshy, one-celled, two- 
valved, opening round the apex. 
Seed solitary, round, invested in a complete, thin, white, scabrous 
aril, which with the seed, as in the germ, is attached to what 
was the partition, now pressed to one side by the abortion 
of three-fourths of its original contents. Integument single, 
when recent orange, but soon changes to a chestnut colour, 
smooth and spongy; a long white umbilicus, strongly marked 
on the side of attachment. 
Albumen none. 
Embryo inverse. Cotyledons two, (hemispheric,) conform to the 
seed, firm, green. Plumula small, two-lobed. Radicle su- 
perior, small, 
OBSERVATIONS. 
The bark, leaves, and tender parts possess a considerable share 
of a peculiar bitter taste ; and the cold infusions thereof, on the 
addition of a little sulphate of iron, became black, two principles 
very generally found amongst the plants of this natural order, 
which grow in India.

Sandoricum Rumph. amb. 1. s. 177. €. 64. 
OBSERVATIONS. 
This elegant tree, a native of the Molucca Islands, was intro- 
duced into the Botanic Garden at Calcutta, by the late Colonel 
Kyd, about fifteen years ago: the largest is now about thirty feet 
high, with a perfectly straight trunk ; smooth greenish coloured 
bark, and a very large, almost round, very ramous, ever-green 
head. Flowering time in Bengal the month of February. 
DESCRIPTION. 
Leaves alternate, petioled, ternate, about a foot long: 
Leaflets ovate, entire ; upper side smooth except when young ; 
downy underneath, from five to seven inches long, and three 
or four broad. 
Petioles round, when young downy. 
Stipules none. 
Panicles axillary, diffuse, often longer than the leaves, and drooping. - 
Bractes oblong. 
Flowers numerous, small, yellow. 
Calyx beneath, campanulate, five-parted; divisions rounded, 
downy. 
Corol: Petals 5, linear-oblong, obliquely emarginate, expanding. 
Nectary double ; the exterior cylindric, with mouth 10-toothed ; 
interior about one-fourth the length of the exterior, enve- 
loping the germ, and base of the style, mouth ten-toothed. 
SANDORICUM INDICUM. 58 
Filaments none. Anthers ten, affixed to the inside of the mouth of 
the exterior nectary. 
Stigma large, five-parted. 
Berry globular, size of a small orange, somewhat 5-sided, a little 
downy, when ripe of a dull yellow colour ; pulp firm, in 
large quantity, white, and acid. 
Seeds from one to five come to maturity, reniform, immersed in a 
soft white pulp, which adheres firmly to the hard exterior 
white integument of the seed ; under which there is a 
second, firm, brown coat. 
OBSERVATIONS. 
The fruit abounds in a firm, fleshy, agreeable, acid pulp, which 
forms a covering of nearly half an inch in thickness round the 
white gelatinous pulp in which the seeds are lodged; these two 
sorts of pulps are separated by a slender, brownish integument. 
BUCHANANIA. 
DECANDRIA MONOGYNIA. 
GENERIG CHARACTER. 
Calyx 5-toothed. Petals 5. Nectary double ; the exterior a cre- 
nulate cup between the filaments and germ; the zmner 4 
subulate bodies on one side within the former. Germ su- 
perior, one-celled, one-seeded ; attachment from the bottom of 
the cell to the apex of the ovule. Drupe with a one-seeded 
nut. Embryo transverse, no albumen. 
262. BUCHANANIA ANGUSTIFOLIA. 
Arboreous. Leaves linear-oblong, emarginate. Panicles ter- 
minal. 
OBSERVATIONS. 
A small, slow growing tree, a native of the southern part of 
the peninsula of India, from thence introduced, by Dr. Francis 
Buchanan, into the Botanic Garden at Calcutta in 1802. In 1808 
the largest of the young trees blossomed in May and June ; and 
the fruit take nearly one year to come to maturity. 
DESCRIPTION. 
Trunk (of our young trees) straight, 12-15 inches in circumference, 
4 feet from the ground, Bark very smooth and ash-coloured. 
Branches numerous spreading, and abounding in branchlets and 
foliage ; general-height of the trees 20-25 feet. 
Leaves alternate, approximate, petioled, linear-oblong, entire, 
obtuse, or emarginate ; of a firm texture, and smooth on both 
sides ; length from three to six inches, and from 1 to 24 broad. 
Petioles round, smooth, about an inch long. 
Stipules scarce any. 
Panicles terminal, and from the exterior axils, smooth. 
Flowers numerous, small, white. 
Bractes at the divisions of the panicle, very small. 
Calyx five-toothed, greatly shorter than the corol. 
Petals five, long-ovate, spreading ; margins recurvate. 
Nectary double, as in B. latifolia. Extervor a thick crenulate cup
