Inflorescences cauli-to ramiflorous (to axillary), branching basally to mainly along the terete, subsericeous, 1.3-18 cm long axis; first order branches up to 8.3 cm long; cymules cincinnate, (l-)3-4-flowered; bracts and bracteoles triangular, outside hirsute, inside glabrous; bracts 0.5-1 mm long; bracteoles 0.2-0.5 mm long; pedicels 1.8-5 mm long, completely sericeous. Flowers 3.5-4 mm in diam. Sepals 5, ovate, margin pilose, with glands, outside and inside glabrous, pale green; 2 outer smaller ones 0.7-1.4 by 1.1-2 mm; 3 inner larger ones 1.8-2.8 by 1.5-3 mm, margin petaloid. Petals 5, ovate to elliptic (to obovate), 1.7-2.8 by 0.5-1.3 mm, white; claw 0.2-0.4 mm high; margin and less so outside pilose, inside glabrous, apex rounded to acute; scales 0.7-1.6 mm long, free, basally not auriculate; crest clavate, stipitate, apex lobed. Disc interrupted. Stamens 8; filaments 1.2-3.5 mm long, completely pilose, especially basally pilose, white; anthers 0.4-0.6 mm long, glabrous to subpilose. Pistil: ovary 0.3-0.6 mm long, sub-hirsute; style and stigma 0.2-0.6 mm long. Fruits with 1-3 well developed lobes, 1.4-1.9 by 1.3-2.4 cm, smooth to rugose, glabrous, not dehiscing to only (partly) dehiscing when completely ripe, red when fresh, blackish when dry; stipe 1-1.5 mm high, broadly obconical; margin blunt; lobes 11-15 by 9-15 mm, widening towards the axis in transverse view; wall at suture up to 3.5 mm thick; septa complete. Seeds obovoid, c. 8 by 7.5 mm; arillode without a pseudo-funicle, basal rim present; hilum c. 1 mm long.
