A shrub 8 feet high, with slender branches, called “jasmin del monte,” because of its 
odoriferous flowers. The leaves are ¿-34 in. long, 1-11 in. broad, on petioles 2-3 lines 
long; the panicles are 11-2 in. long, on slender peduncles 6-9 lines long; pedicels 
2-3 lines long; sepals $ line long; tube of corolla 7 lines long, segments 5 lines long.

A well-known species, but insufficiently described. Sloane’s specimen agrees well 
with his drawing (tab. 186). Lunan describes it as a tree 15 feet high, with a trunk as 
thick as a man's leg, covered by a smooth whitish bark, and having tortuous branches; 
its branchlets are curved, with axils 11 in. apart; leaves patently opposite along the 
terminal branchlets, oval-oblong, subacute at the base, suddenly contracted at the apex 
into a short acumen, lucidly green above, entire on the margins, with several patently 
divarieating nerves, 4—5 in. long, 2-23 in. broad, on straight petioles 1-13 in. long; 
panicles lateral, 1-13 in. long, branching from the base, and bearing several approxi- 
mated yellow odoriferous flowers, on pedicels 3 lines long; sepals ovate, rounded, mem- 
branaceous, veined, imbricated, each having 3 short inner lanceolate scales; tube of 
corolla narrowly cylindrical, a little wider above, 6-8 lines long; its segments, 5-6 lines 
long, are obliquely ovate and expanded horizontally on one side, and simply convoluted 
sinistrorsely in zestivation; the stamens are inserted in the upper portion of the tube; 
anthers cuspidate at the apex, extending a little beyond the mouth; a semi-5-lobed 
disk, 4 shorter than the 2 free, adpressed, striated ovaries; style slender, surmounted by 
a thickened, deeply 5-sulcate clavuncle, having a membranaceous expansion at its base,
