The true guttapercha tree, perhaps the most valuable of all the trees of the 
Peninsula. It gives the “ Taban ” Gutta or “ Taban Merah.” It has become very 
scarce in a wild state, but is now being much planted, so perhaps it may soon again 
become common (see also H. C. Hill, Reports on Forest Conservancy in the Straits 
Settlements and the Federated Malay States, and Burn-Murdoch in “ Indian Forester,” 
XXXI. 309, “ Some Facts about Gutta Percha.”) Ridley, in Trans. Linn. Soc. III. 
(1893), 317, says the tree was seen by him in several places in the Tahan woods, and 
that a considerable amount of guttapercha is collected there. 
Var. oblongifolia. A large tree ; stem reaching 80 feet in height 
and up to 2 feet in diam. Leaves larger than in the typical form, 
obovate-obloug or lanceolate-oblong ; longer, abruptly acuminate, 
reaching 7 in. in length and 3 in. in breadth, rather more con- 
spicuously golden-pubescent. Flowers similar but a little larger, 
pedicels a little shorter. Fruit rather larger, less acute at top. P.

We are unable to find sufficient characters for separating this, as a species, from 
P. Gutta , as is done by Burck. The specimens available seem to point to a regular 
series of intermediates, so that it can scarcely be even maintained as a variety. It is 
possible that P. malaccense and P. formosum, Pierre in Bull. Soc. Linn. Par. I. 498, 
are both forms of P. Gutta, but we have seen no specimens. Beccari in “ Nelle
