Leaflets subsessile, opposite to alternate, elliptic, 3.6-17.1 by 1.2-6.3 cm, index 2.1-3.8, Asymmetrical, acroscopic side slightly broader, sub)coriaceous, usually punctate; base attenuate; margin entire, flat; apex (acute to) acuminate to cuspidate (to caudate), usually mucronulate; upper surface glabrous, (puberulous on midrib); lower surface duller, smooth, no papillae, subglabrous, domatia in at least some leaflets a single small sac on basiscopic side in axil of second nerve; venation on upper side (slightly sunken to) flat (to raised), raised below; nerves 0.2-3.8 cm apart, marginally looped and joined, often less distinctly so in lower part of leaflets; veins laxly reticulate, indistinct. Inflorescences ramiflorous (to axillary), unbranched to branching basally and along the terete, sericeous, 1-13.3 cm long axis; first order branches up to 6.2 cm long; cymules cincinnate to dichasial, (l-)3-4(-5)-flowered; bracts and bracte-oles triangular, outside hirsute, inside glabrous; bracts 0.4-1 mm long; bracteoles 0.2-0.6 mm long; pedicels 1.9-5.5 mm long, sericeous except for the subsericeous articulate part. Flowers 3.5-4 mm in diam., slightly fragrant; buds green-white. Sepals 5, ovate, margin pilose, outside and inside glabrous, white; 2 outer smaller ones 0.7-2 by 0.8-2.3 mm, margin with glands; 3 inner larger ones 1.8-3.2 by 1.5-3 mm, margin petaloid, at most with few glands. Petals 5, ovate to obovate, 1.5-4.2 by 0.7-1.6 mm, white; claw 0.2-0.5 mm high; margin and usually outside pilose, inside subglabrous, apex acute; scales 1-1.7 mm long, free, basally not au-riculate, margin not distinctly membranous; crest clavate, stipitate, apex lobed. Disc interrupted. Stamens 8; filaments 1.3-3.7 mm long, pilose, especially basally, white; anthers 0.6-0.7 mm long, slightly pilose. Pistil: ovary 0.3-1.5 mm long, sub-hirsute; style and stigma 0.1-1.2 mm long. Fruits with 1-3 well developed lobes, 1.1-2.9 by 1.1-3.5 cm, completely dehiscent, smooth to rugose to ru-gosely ribbed, glabrous, red when fresh, blackish when dry; stipe 0-2 mm high, slender; margin blunt; suture usually highly convex, lobes almost touching; lobes 10-18 by 9-22 mm; septa complete. Seeds obovoid, c. 8.7 by 5.2 mm; arillode without or with a small pseudo-funicle, but always with a basal rim; hilum c. 1.3 mm long.
