Shrub or tree, up to 30 m, 40 cm dbh. Twigs glabrous to minutely hairy. Petiole (4-)5-7 mm, glabrous to minutely hairy. Leaf-blade 5-20 by 2-7 cm, margin often irregular, sometimes shallowly cre-nate because of glands; above usually brownish, midrib narrowly sunken; beneath more or less con-colorous, secondary nerves 5-9 pairs, forming a rather distinct intramarginal nerve; glands rather numerous, c. 0.4-0.8 mm diam., scattered but at least 8 present on the leaf margin itself, other glands (4-)6-10. Inflorescences often several together on the secondarily thickened nodes, shorter than the leaves. Pedicel c. 3-4 mm, rather sparsely to rather densely minutely (woolly-)hairy. Sepals mostly nigrescent, glabrous to minutely hairy inside; outer sepals 3-3.8 by 1.8-2.2(-2.7) mm; inner sepals 3.8-4.8(-6) by 2.3-3.2(-4.5) mm. Petals white to light yellow, when dry light brown to dark orange, inside minutely hairy only above base; carina 6-7(-8) mm long; other petals 8-9 mm long, lateral petals 3-4 mm wide, upper petals 1.5-2 mm wide. Stamens: filaments glabrous; anthers 0.4-0.6 mm long, shortly hairy at base, ciliolate along slits, often cohering around the stigma. Ovary subsessile; style glabrous; ovules 8-14. Fruit sessile, globular, 1.5-2.2 cm diam., smooth, dark reddish, somewhat shiny; pericarp thin, brittle; pedicel 3-6(-8) mm long. Seed often (sub)apical.
