Foreste di Borneo," p. 558, suggests the identity of the latter species with P. 

 ohlongifoliwn.

 (1885), non Burck. A large tree ; branchlets dark brown, marked by 

 prominent scars 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-pubescent 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. Fntit 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 {jiart), 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 ; fridt oblong ; 

 branchlets grey, very rough with scars of fallen leaves and flowers. 



Perak : Wray 511 {part), 518.

 (see Teysmann's specimen in Herb. Kew).

 30 (1885). A large handsome tree ; the stem reaching 80 to 120 feet in 

 height and 2-5 to 3 feet in diam. ; branchlets dark brown, innovations 

 rusty-pubescent; leaf -bud scales lanceolate, ciliate, about -1 in. long. 

 Leaves coriaceous, glossy-green ; obovate, obtuse and often emarginate
