petiole J inch. Panicles lax, terminal, with a few wide spread- 
ing branches. Flowers small on pedicels \ inch long pubescent. 
Calyx 5, lobed lobes ovate, hairy, pink, J inch long. Corolla 
tube short and broad, nearly £ inch long, hairy within lobes, 
oblong a little longer and blunt, pink with white tips ; a ridge 
runs round the corolla mouth. Stamens 5 short, filaments 
very short from base of corolla, anthers arrowshaped eonni- 
vent. Pistil conic. Capsules twin long slender, cylindric, not 
distinctly torulose red, 15 inches long, £ inch through. Seeds 
numerous, oblong, linear, blunt at both ends, terminated by a 
large sessile plume. 
This is a beautiful plant when in flower, the flowers though 
small being produced in great abundance and of a beautiful rose 
pink. It is known as Akar Getah Grip Putih, Serapit and Sedang* 
and occurs in Singapore, Malacca and Perak. 
The rubber is considered good. 
Trees. 
Dyer a costulata, Hook. fil. — A very large tree attaining a 
height of 200 feet, with grey rough bark. Branches brown. 
Leaves in whorls of six, thinly coriaceous, oblong to oblong 
lanceolate, blunt at both ends, nerves about 15 pairs, 9 inches 
long by 6 wide, dark green above, paler beneath, petiole 1 
inch. Panicles on peduncles 4 inches long, or less with few 
branches, axillary. Flowers small, J inch long. Calyx short with 
blunt lobes. Corolla tube as short or shorter, lobes lanceolate, 
white. Stamens very short, filament very small, anthers conic 
brown. Style short conic. Fruit a pair of capsules deflexed, 
woody over a foot long, fusiform blunt, splitting along the upper 
edge where there is a thin broad margin. Seeds numerous, very 
thin flat, oblong with a broad wing on each side, 2 inches 
long and 1 wide. 
“Jelutong” — Common over the whole Peninsula. This tree 
flowers after it has shed its leaves and when the young leaves are 
coming out. The leaves vary a good deal and are often smaller 
than described, and in young shoots, stumps, etc., very much 
larger. This variation in specimens is perhaps the cause of two 
species of Dyera being described in the Flora of British India, 
viz., D. costulata and D. taxi flora. I have not recognized more 
than one species here, but the Malays do talk of two plants, Jelu- 
tong and Jelutong Pipit. This is the plant which produces the 
Jelutong rubber, in the Peninsula, and if Alstonia costulata , Miq., 
is the same plant (it is only very imperfectly described), it is 
also a native of Sumatra. Miquel gives the name Getah 
Labuai for it. 
I have received another plant from British North Borneo at 
Labuk Bay under the name of Getah Jelutong from Mr. Wade. 
This, a branch with leaves only, has the leaves scattered not in 
whorls, they are rather thin textured, very long and narrow lan- 
ceolate, acuminate, 8 inches long, 2 inches wide, with a slendt- 
petiole an inch long. It is probably not a Dyera at, all, but 
further material is required.
