Tree, 5-25 m, 60 cm dbh. Twigs densely set with short and long hairs, longer hairs 0.3-0.8 mm long. Axillary buds 1-3 mm long, hairy like the twig. Petiole (4—)8—14(—16) mm, hairy like the twig. Leaf-blade (6-)9-22 by 3-9 cm, apex cuspidate or sometimes acuminate; above greyish green, in basal part sometimes sparsely hairy especially on the nerves and midrib, midrib distinctly sunken, nerves and intramarginal nerve slightly sunken to flat and rather obscure, venation obscure; beneath brownish, hairy like the twig, rarely rather sparsely hairy, secondary nerves 8-11 (or 12) pairs, strongly prominent, forming a strongly prominent intramarginal nerve; glands (7—)10 or more, scattered, (0.2-)0.3-0.4(-0.6) mm diam., basal glands 0.9-1.2 mm long. Inflorescences about as long as the leaves; axes ribbed, very densely patently brownish hairy in the basal part; flowers with 3 together. Pedicel 1.5-6.5 mm, ribbed, very densely patently brown pubescent, rarely shortly hairy. Sepals persistent in fruit, greyish hairy; outer sepals 2.1-3.2 by 1.7-3 mm, with 2-4 glandular spots; inner sepals 3.5-5.3 by 2.4-3.4 mm, distinctly keeled. Petals white or yellow, when dry brownish orange, the longest one 9.5-10.5 mm long; carina more or less densely appressedly hairy outside, sparsely appressedly hairy inside in middle part; other petals ciliate in basal half, glabrous outside, upper petals reflexed. Stamens: filaments rather sparsely appressedly hairy till apex; anthers (0.75-)0.8-1.2 mm long, usually cohering around the stigma, ciliate along slits. Ovary sessile, distinctly ribbed, glabrous or sometimes hairy on 2 ribs down to halfway; style reflexed at end of anthesis; ovules (6—)8—12. Fruit (immature) ovoid, very sharply beaked, with 8 or more distinct ribs, finely pustulate to tuberculate, dull, greyish brown; pericarp thick, hard; pedicel crowned by persistent sepals.
