authority of Zea, has joined this with Cinchdna lancifdlia of 
Mutis, with which it has not the least affinity. Called 4smonich

2-celled (f. 87. 6.), dehiscing at the dissepiment from the apex,

Don, prod. fl. nep. p. 189. A 
small branching tree, with terete 
pubescent branches; elliptic, acu- 
minated leaves, which are gla- 
brous above and villous on the 
veins beneath, on short petioles. 
Cymes terminal, many-flowered. 
Flowers rose-coloured, rather 
fleshy, sweet-scented. Stipulas 
solitary on each side, broad at 
the base and cuspidate at the 
apex, longer than the petioles. 
Segments of calyx deciduous. 
It is impossible to conceive any 
thing more beautiful than this 
tree, when covered with its nu- 
merous cymes of pink-coloured very fragrant flowers. 
Very-grateful-scented Luculia. Fl. Aug. Sept. Clt. 
Tree 16 to 20 feet. 
Cult. A very good rich light soil will suit this tree; and 
cuttings may be rooted in sand under a hand-glass, but with 
great difficulty.

Anthers linear, exserted. Stigma 2-lobed. Capsule 2-celled, 
dehiscing at the cells, many-seeded ; valves ventricose, mem- 
branous. Dissepiment complete. Seeds girded by a membra- 
nous, reticulated border, which is bifid at the base.—Trees, 
natives of the East Indies, with compressed branches: coria- 
ceous, petiolate leaves; deciduous, glandularly ciliated stipulas ; 
and small, inconspicuous, greenish, pubescent flowers, disposed 
in fascicles, the whole forming racemose panicles. Floral leaves 
one under each branch of the panicle, lanceolate, convex, veiny, 
on long petioles, similar to the large calycine teeth of Musæ'nda, 
but placed in a different situation.

parts of the Circars, and chiefly of the valleys, where it grows 
to be a large tree. It is called Bundaroo in the Telinga lan- 
guage. Cinchdna excélsa, Roxb. cor. 2. p. 3. t. 106, Tratt. 
tab. t. 170. The lower pair, or two of the ramifications of the 
panicle, are ornamented each with a pair of coloured floral 
leaves. Panicles terminal, large. Flowers fascicled, small, 
greenish white. The infusion of one fresh leaf in water all 
night had little taste, but struck quickly a deep purplish blue 
with a chalybeate. The two inner coats of the bark (the outer 
light spongy stratum is tasteless) possess both the bitterness and 
astringency of Peruvian bark, and when fresh in a stronger 
degree; the bitterness is not so quickly communicated to 
the taste on chewing the bark, as that of the former, but is 
much more durable, and chiefly about the upper part of the 
fauces. The wood is firm, close-grained, of a pale mahogany 
colour, and very useful for many purposes. F
