Stipules ovate to ovate-elliptic, 5-7 by 2-5 mm, free, usually with one large, hollowed gland outside, ciliate.
Stamens 15-40, filaments up to 3.5 mm, anthers 0.3-0.5 mm long.
Ovary with few hairs or glabrous, style up to 4.5 mm long.
Fruits transversely ellipsoid, 5-7 by 6.5-10 mm, exocarp sparsely hairy or glabrous, black when ripe, mesocarp thin, endocarp glabrous or with hairs inside.
Seed with glabrous or hairy testa.
Notes
Only few collections seen from Borneo, and only two sterile collections from Sumatra. The relatively large, hollowed glands in the stipules are characteristic. The seeds are glabrous in five of the fruiting specimens seen (most of them immature), hairy in only one specimen. Judged from the fruits, the ovary may sometimes be more densely short-hairy than seen in the flowering specimens.
