WlLLUGHBEIA. 
W. firma, Bl. — A large climber about 4 inches through. Bark 
thick black covered with brown warts, in section red. Branches 
black warted, tendrils long and slender on the ends of the 
branches. Leaves coriaceous, dark shining green, lanceolate, 
acute, 4 inches long by wide, petiole thick, nearly £ inch 
long, nerves about 10 to 15 pairs. Flowers in short axillary 
cymes, about as long as the petiole on stout peduncles, white 
sweet-scented, pedicels very short and thick. Bracts ovate, 
lanceolate as long as the pedicel. Calyx £ inch long, lobes 5, 
rounded ciliate on the edge. Corolla more than twice as long, 
tube dilated about the middle. Anthers 5, ovate acute, filaments 
very short, half-way down the tube adnate to the sides. Ovary 
, globose style shorter than the calyx, stigma conic. Fruit 
rounded, oblong or globose, about 4 inches long and 4 inches 
through, dull green or orange coloured, seeds numerous, soft, 
oblong, flat, inch 1 long, T inch wide, and rather more than 
| inch thick, with violet testa, cotyledons tinted violet. 
Common in the Malay Peninsula from Singapore to Malacca, 
Penang and Perak, also Sumatra (Lampong) and Borneo. 
Natives names, Getah grip, gegrip, grit, gegrit, or singatip

Borneo. 
This is perhaps the best of all the Getah grips, and is the most 
sought after. It grows readily from seed, though not very fast, 
having a habit of making long slender twiggy stems, especially if 
grown in the open. In forests it climbs to the tops of the highest 
trees, and the stem eventually becomes very thick. It is distin- 
guished from W , coriacea, by the longer leaves with more nerves, 
longer peduncles and cyme, larger calyces. 
The first account of the collecting of rubber from this plant is 
that of Murton, who published it in the Kew Report of 1880, 
p. 46, which is long out of print and unprocurable, but extracts 
from it are printed in Morris’ Cantor Lecture, p. 43. Murton 
mentions two varieties. One he describes as having dark bark 
with lighter coloured warts, is the true plant. The other with 
light cork coloured bark is certainly something else, probably 
Leuconotis. His account of the collecting is as follows: — ‘‘The 
stem is ringed at intervals of 10 to 12 inches, and the milk allowed 
to run into vessels made of palm leaves, cocoanut shells, or 
anything available for the purpose ; it continues to flow for a 
time, but after flowing for ten minutes it becomes watery and 
thin, one plant will yield from 5 to 10 catties of the coagulated 
caoutchouc ; when raw, it has the appearance of sour milk, and 
to coagulate it the natives add salt or salt water. When 
freshly coagulated it is quite white, which gradually changes to 
a darker colour. It keeps white inside and, on cutting, produces
