by (2-)3-6(-7.5) cm, coriaceous; apex long acuminate to acute; base cuncate or rounded; surfaces
concolorous, dark brown when dry, glabrous above, glabrescent beneath; nerves (5-)6-8(-9) pairs,

mm long. Sepals 3, elliptic-oblong, c. 3.5 by 2-2.5 mm, minutely hairy inside. Stamens
6; filaments 1-1.5 mm long; anthers linear, 3-3.5 mm long, sometimes hairy
along both sides of the connective. Ovary c. 1.5 mm long, whitish hairy; style 1.5-2

In undisturbed mixed dipterocarp and keranga forests up to 400 m altitude.
