and a half to three feet in circumference, Bark brownish, and sca- 
brous, with longitudinal fissures. Branches numerous, dividing much, 
spreading, and rising in every direction, forming nearly a spherical 
head. Young shoots round and smooth; extreme height of our largest 
twelve or thirteen year-old trees, about twenty-five feet. — Leaves 
opposite, petioled, oblong, generally obtuse, smooth, entire, glaucous. 
underneath : length from one and a half to three inches.—Petioles. 
scarcely one-fourth the length of the leaves, smooth.—Stipules none. 
Thyrsi axillary and terminal, much shorter than the leaves. Pedi- 
cels opposite, the lower pair of each thyrsus generally three-flower- 
ed.— Flowers numerous, small, when they first expand strawecolour- 
ed, changing to.2 deep ferrugenous purple, inodorous, as are all the 
-exterior parts of tlie growing plant, even when bruised.— Calyr ones- 
leaved, campanulate ; border four-parted ; segments ovate, smooth, 
base of the bell only permanent.—Corol none, except the calyx, or- 
nectarial glands are so called.— Nectary of four, roundish, sessile, 
` thick, fleshy glands, on the mouth of the bell of the calyx, alternate 
with the segments of its border, and when the flower first expands, 
the most coloured part, entire. In Sirium (now Santalum) myrtifoli= 
um, they are lobate.— Filaments four, alternate with the nectarial 
scales, and of the same length, smooth, but behind each there rises a 
tuft of white hairs from the disk of the segments of the calyx, per- 
fectly distinct from the stamina, but of the same length, the ends of 
. these long, white, woolly hairs adhere to the back of the small, two- 
lobed anthers.— Germ semi-superum, one-celled, containing one Co- 
nical seed, attached to the bottom of the cell. ` Style, length of the 
tube of the calyx.— Stigma three-nerved, four-lobed. Berry pyren- 
ous, round, smooth, when ripe black, and succulent, size of a cher- 
ry, aüd crowned with the remaining calyx, óne-celled.— Nut solitary, 
spherical; three small, equisdistant elevations from the apex run a 
little way down the sides. — Seed conform to the nut. — Zntegument 
single, soft, white, spungy, lining the aut, and aliii ‘to it and the 
seed also.— Perisperm conform to the seed, white, amygdaline.— 
Embryo inverse, subulate, nearly as long as the vertical diameter of
