W. grandi flora, Dyer? Is a strong climber with rather narrow 
oblong cuspidate, thin textured leaves with about 30 nerves. 
Panicles rather lax, half an inch long. Flowers an inch long with 
broad lobes, the mouth of the tube is hairy, tube swollen at the 
base. The panicles and large calyx are pubescent. 
“Akar Jitan.” It occurs in Singapore, Malacca and the Din- 
dings. 
This is easily recognized by its very large showy flowers. The 
leaves resemble those of the last species. In the description of 
W. grandi flora in the Flora of British India the leaves are de- 
scribed as very thickly coriaceous and with only 4 to 7 pairs of 
nerves, which certainly does not agree with this species. If it is 
not IT. grandi /lor a, Dyer, it must be undescribed. 
Chilocarpus . — The species of this genus which is distinguished 
from Willughbeia, by its yellow or orange flowers and fruit split- 
ting when ripe, containing numerous albuminous seeds, though 
very milky, climbers give, but a poor amount of caoutchouc. The 
stems are usually at least rather slender, with pale loose baik, 
their habit being altogether more like that of Leuconotis than 
Willughbeia. 
Ch. enervis , Hook, fil., which has long beenin cultivation m the 
Gardens, though flowering regularly, has never fruited, and all 
attempts to propagate it by cuttings or layers have failed. The 
stems are slender, about \ inch through, covered with brown 
wrinkled bark, the leaves are thick and nerveless. 
Melodinus — Includes three or four species or climbers with 
white flowers in axillary clusters, the fruit green or yellow globose, 
with a hard rind, the seeds numerous, wrinkled, enclosed in a good 
deal oi pulp. M. Orientalis, Bl. the commonest, produces an in- 
ferior sticky caoutchouc mixed with the other Get ah Gerips, but 
it does not seem to be a very common plant, occurring here only 
in Penang, though it is met with also in Java and Sumatra. Of 
our other species, M. coriacea, Oliv, a native of Penang, and M. 
micrantha , Hook, hi., a rare plant occurring in Singaporeand Ma- 
lacca nothing is known as to their rubber-producing qualities. 
Leuconotis.— This genus of five or six species is represented 
fieit; W three kinds, all climbers (not erect shrubs as stated in 
the Flora of British India), small compared with the Wiliughbeias, 
but producing useful rubbers. The flowers are in close axillary 
panicles, orange coloured, the corolla tube is shorter in propor- 
tion to the size of the flowers than in Willughbeia , and the lobes 
are thicker and shorter. The fruits are comparatively small with 
few seeds. . t „ . 
L. Griffiths Hook, fil.— Stem about 2 inches through. Bark 
light grey, rather rough. Leaves opposite lanceolate, acute or 
acuminate, ratherthick, nerves about 7 pairs, dark green, 6 inches 
long and 3 inches wide, petiole* to 2 inches long. Panicles 
axillary on stout peduncles an inch long, rather ciowded. 
Flowers few. Bracts ovate. Calyx lobes lanceate blunt ovei- 
lapping nearly as long as the tube. Corolla | inch long, 
tube thick, widest and square at the base, yellow lobes ovate
