revolute margins, having above immersed, almost evanescent nerves, beneath punctulate- 
scabrid, with short sparse soft hairs, 3-4 in. long, 13-2 in. broad, on thick petioles 4 lines 
long; raceme lateral, shorter than the leaves; peduncle thick, stiff, glabrous, bearing 
many densely crowded smallish flowers, on pedicels viscidly puberulous, nearly 9 lines 
long, thickened above; sepals obtusely ovate, scarcely 1 line long, altogether with about 
8 minute internal scales ; tube of corolla narrowly cylindrical for half its length, 8 lines 
long, a little swollen above; segments obliquely ovate, 4 lines long; ovaries enclosed 
within an urceolate disk of 5 truncated subconnate lobes.

A twining shrub, with slender flexuose branchlets, lenticellate and ferruginously sub- 
hirsute; leaves elliptic or lanceolately oblong, obtuse at the base, shortly acuminate, 
rigidly membranaceous, dark green, opake, and glabrous above, paler and hirsute be- 
neath, with darker nerves, 2-3} in. long, 10-20 lines broad, on petioles 3 lines long; 
raceme lateral, on a slender peduncle 6-8 lines long, with many minute caducous 
bractlets ; flowers on twisted, slender, puberulous pedicels ; sepals lanceolate, acuminate, 
2$ lines long, unequal, puberulous, with membranaceous ciliate margins; corolla 10} 
lines long; tube longer than the sepals, pubescent, funnel-shaped above, contraeted near 
the middle, and there staminigerous ; segments sparsely pubescent on both sides, with 
white margins, half as long as the tube; disk urceolate, margin shortly cleft into 5 fleshy 
lobes, half as long as the 2 ovaries.

vidi. 
A climbing glabrous plant, not to be confounded with the Echites angustifolia of Ben- 
tham or with that of Poiret. Leaves oblong-lanceolate, obtuse and subcordate at the 
base, very acute, 4 in. long, i-i in. broad, on petioles 6 lines long; panicle lateral, 
nearly 4 in. long, on a dichotomously divided peduncle, bearing many flowers on re- 
flexed pedicels 6 lines long ; sepals obovate-oblong, 2 lines long; tube of corolla 9 lines 
long, lower part pilose within and staminigerous in the middle; disk urceolate, of 5 
fleshy truncate lobes, unequally connate, a little shorter than the 2 ovaries. 
It certainly does not belong to Odontadenia; it is a species apparently very close to 
the preceding.

A subscandent plant, with very slender striate branches, the axils 21-3 in. apart; 
opposite leaves linear-oblong, shortly cordate at the base, subacute and mucronate at the 
summit, with revolute margins, rigidly coriaceous, suleate above along the middle, convex 
on each side of the midrib, pale green above, sparsely and softly pubescent, with about 
12 pairs of patent arcuate immersed nerves, pale yellow and pruinosely velutinous be-
