Besih, Akar Jala. 
This can be identified by its short conic pods, very broad in 
proportion to their length, very unlike any other of our species. 
The plant, as I have usually seen it, is not a large one, but it pro- 
bably can attain a greater size. U. esculenta, Benth. Tavoy 
and Pegu, is said by Kurz to be the same species. 
The rubber is good, but the plants which I have seen wild, did 
not produce a very large amount of latex. It is mixed with 
other rubbers. 
U. Malaccensis, Hook. hi. — A fair-sized climber, glabrous ex- 
cept the infloresence. Leaves rather stiffly, coriaceous, elliptic 
or ovate, lanceolate, acuminate, 6 to 7 pairs of nerves, prominent 
on both sides, 4 inches long, inch broad, petiole \ inch long. 
Panicles terminal small compact, peduncles short pubescent. 
Flowers as large as in U, elastica. Calyx lobes oblong, lanceolate 
obtuse, pubescent, nearly as long as the corolla, which resembles 
that of U. hicida. Bracts persistent rather long, oblong, obtuse, 
pubescent. Capsules twin very long, cylindric, acuminate 6 — 7 
inches long, £ inch through.

U . Maingayi, Hook. hi. — Somewhat resembling U. elastica , but 
quite glabrous with stiff coriaceous leaves and long cylindrical 
slender acute capsules, occurs in Singapore and Malacca, but is 
not common. I have no information as to its rubber. 
U . brachysepala , Hook, hi. — A fairly stout creeper. Leaves 
rather thin textured, elliptic acuminate, 3 — 4 inches long, 2 inches 
wide, glabrous, father dull green, petioles | inch long. Panicles 
terminal usually rather large with stout peduncles pubescent. 
Flowers numerous green. Calyx pubescent, lobes 5, lanceolate. 
Corolla white, pubescent lobes, ovate, acute, pubescent. Stamens 
as in U. lucida. 
Akar Gegrip Merah. A native of Singapore and Malacca. 
The rubber is considered good by the Malays, who mix it with 
other grips. The latex is not very abundant and is rather slimy 
in cultivated plants. 
U.torulosa, Hook. hi. — Leaves small, ovate, cuspidate, coriace- 
ous, glabrous, 3 inches long and r wide, petiole £ inch, nerves 
5 or 6 pc irs. Panicles small, terminal and axillary, about an inch 
across, short pubescent, bracts linear, oblong, obtuse. Flowers 
sma 1 ! pubescent. Calyx lobes linear pubescent. Capsules over a 
foot long, slender, dilated at intervals where the seeds are. Seed 
about S, oblong with a red tuft at the tip and a plume j inch 
long.
