(1885), non Burek. A large tree ; branchlets dark brown, marked by 
prominent sears of fallen leaves; innovations minutely ferruginous- 
pubescent. Leaves coriaceous ; oblong-obovate, abruptly and shortly 
acuminate at apex, cuneately attenuate at base ; glabrous above, densely 
appressed-golden-pubeseent beneath, finally glabrate, margins recurved, 
5 to 8 in. long, 2-5 to 3 in. broad ; midrib prominent, thick, impressed 
above; main-nerves 14 to 18 pairs, irregular, sometimes branched, '4 to 
•5 in, apart, starting at an angle of about 60° with the midrib, curved 
near the margin to meet in a rather faint looped intramarginal nerve, 
secondary nerves few ; reticulations few, horizontally transverse , 
petiole 1 to 1-5 in. long, somewhat thickened at base, minutely rusty- 
pubescent, channelled above and bordered for some distance by the 
decurrent margins of the blade ; stipules minute, falcate, caducous. 
Calyx-lobes 6 ; 3 outer rather thicker than 3 inner, ovate, sub-acute, 
densely ferruginous-pubescent, "25 in. long. Fruit a nearly globose 
berry, 1 in. long and about -75 in. in diam. Seeds oblong ; testa

Penang : Curtis 3582. Perak : Curtis 3631, 3638, 3724 — on the 
hills up to 2,500 feet; Wray 511 (part), 590; Douglas; Phillips. 
Selangor : Curtis 3763, 3764. Singapore : Maingay (K.D.) 983 (the 
No. 1948 quoted by Pierre) ; Jas. Collins (a pustulate form apparently 
diseased). 
This species gives apparently the “ taban sutra ” or “ taban putih” guttapercha, 
which is not one of the best quality. 
Var. glabrata King & Gamble. Leaves smaller, about 1-5 in. broad, 
glabrate beneath, rarely slightly golden-pubescent ; fruit oblong ; 
branchlets grey, very rough with scars of fallen leaves and flowers.
