Branchlets straight, with short internodes and distinct leaf scars, bark greyish. Stipules rather adpressed, long-triangular, dull dark purple-brown, to 12-15 mm long (shorter on the smaller branchlets), base half-amplexicaul, more or less distinctly keeled and/or striate, initially with minute hairs, long persistent. Petiole 3-7 mm. Leaf blade coriaceous, to (10-)15-27 by (2-)3-6½ cm, widest somewhat above the middle, index (3.5-)3.8-5; base blunt and slightly unequal, top gradually and long-acuminate; midrib narrow, prominent on both sides, major veins c. 13-17 on either side, with often in between a secondary vein half as long, the major ones converging and connected to an intramarginal vein, reticulation rather irregular; margin with minute dark coloured teeth c. ⅓-½ apart; surfaces dull, above olive-green to brownish, beneath somewhat paler, glabrous (youngest leaves unknown); no domatia. Inflorescences axillary (sometimes the subtending leaf gone), axis single or branched, 2-3 cm long; bracts like the stipules but smaller; pedicel c. 4 mm, initially with minute hairs, jointed in the apical part. Sepals rather unequal, the outer ones fleshy, 4 mm ø, outside with some adpressed hairs, the inner ones membranous, 6 by 5 mm, glabrous but ciliate at the top. Petals not very fleshy, rather concave, glabrous, 8 by 3 mm, top slightly cucullate. Androecium 3 mm high, glabrous, filamental tube c. 0.3 part of the total length, free portion of the filaments c. 0.2-0.3 part, anthers 0.4-0.5 part, the dorsal appendage broad, triangular, somewhat longer than the thecae, ventral appendages nearly reaching the top of the dorsal one. Ovary cylindrical, densely soft white hairy; style glabrous; ovules 9. Fruit (only known after dehiscence) with thick leathery valves 2½-3¾ cm long, wrinkled and, especially towards the top, with short soft patent hairs. Seeds 9 in number, obconical, 8 by 7 by 6 mm, with a circular depression at the place of insertion, evenly straw-coloured.
Mixed dipterocarp and kerangas forests at 100-600 m, on sandstone or clayey soil or shale. Fl.--09, fr. March, Aug., Nov.
