A tree rising to 100 ft. tall. Leaves coriaceous, dark green 
above, golden-coppery beneath, obovate obtuse (in old trees) to 
oblanceolate acuminate, base slightly or rather long-narrowed, 
midrib prominent; nerves 20 or more, very fine and inconspicuous; 
3 to 5 in. long, 1-5 to 2-5 in. wide. Flowers in fascicles of 4 or 5, 
axillary on bare part of branches. Sepals 6, brown-pubescent, 
3 outer triangular ovate, inner longer. Corolla white with 6 ovate 
imbricate lobes, -25 in. long. Stamens 12; filaments slender. 
Ovary slightly pubescent, 6-celled; style long, filiform. Berry 
•6 to *7 in. long, oblong, red-pubescent. Seed 1 (rarely 2), oblong 
round at both ends; hilum elliptic covering half the seed, testa 
brown. Hab. Forests; over the whole peninsula as far north 
as Penang, on both coasts. Native names: Getah Taban; Ekor 
Daun Durian (Penang). Use: The Gutta Percha tree. The 
product largely used for deep-sea cables, surgical instruments, 
etc. The tree is now protected all over the peninsula. 
This plant is apparently endemic in the Malay Peninsula except the 
variety Curtisii described below. It was first discovered by Dr. Mont¬ 
gomerie in Singapore in 1845 ( Magazine of Science). He mentions three 
varieties of gutta-percha, viz. Gutta Girek {Getah Grit) W illughbeia ; Gutta 
Taban; and Gutta Percha ( Payena Maingayi); by some accident it appears 
that the name Gutta Percha (Getah percha) was transferred from the Payena 
to the Palaquium (see under Payena Maingayi). 
King, l.c. 193 keeps up the var. oblongifolia, P. oblongifolium of Burck, 
but seems doubtful that it can be kept up even as a variety. It only differs 
in its longer acuminate leaves, and there are plenty of intermediate states. 
It appears to me to be merely a young state of the foliage, and is certainly 
the commonest form.
