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, Eeports 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.") Eidley, 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. ohlongifolia. A large tree ; stem reaching 80 feet in height 

 and up to 2 feet in diam. Leaves larger than in the typical form, 

 obovate-oblong or lanceolate-oblong; longer, abruptly acuminate, 

 reaching 7 in. in length and 3 in. in breadth, rather more con- 

 spicuously golden-pubescent. Floivers 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. formositm, Pierre in Bull. Soc. Linn. Par. I. 498, 

 are both forms of P. Gutta, but we have seen no specimens. Beccari in "Nelle
