Inflorescences axillary to pseudoterminal, branching basally and along the terete to ribbed, subglabrous to sericeous, 1-17.6 cm long axis; first order branches up to 7.8 cm long; cymules cincinnate (to dichasial), 2-4(-7)-flowered; bracts and bracteoles deltate to triangular, outside sericeous, inside glabrous; bracts 0.4-1.3 mm long; bracteoles 0.2-0.6 mm long; pedicels 1.1-4.5 mm long, sericeous except subglabrous above articulation. Flowers 4-4.5 mm in diam. Sepals 5, ovate, margin pilose, with glands, outside and inside glabrous, green to pinkish; 2 outer smaller ones 0.7-2 by 0.6-1.8 mm; 3 inner larger ones 1.8-3.2 by 1.7-3.5 mm, margin petaloid.

Disc interrupted. Stamens 8; filaments 1.1-4.5 mm long, pilose, especially basally; anthers 0.3-0.8 mm long, sparsely pilose, (purplish) pink. Pistil: ovary 0.2-:,mm long, subhirsute; style and stigma 0.1-2 mm long. Fruits with 1-3 well developed lobes, 0.8-.5 by 0.9-2 cm, smooth to rugosely ribbed, glabrous, red when fresh, reddish to reddish black when dry; stipe 1.5-4.5 mm high, slender; margin blunt; lobes 7-11 by 5.5-11 mm; septa complete.
