Inflorescences axillary, unbranched to branching basally on the terete, hirsute, 1.2-6 cm long axis; first order branches up to 1.5 cm long; cymules cincinnate, 1-or 2-flowered; bracts and bracteoles narrowly triangular, outside hirsute, inside subglabrous; bracts c. 1 mm long; bracteoles 0.4-0.8 mm long; pedicels 1-3.2 mm long, hirsute except for the (sub)glabrous articulate part. Flowers c. 3 mm in diam. Sepals 5, ovate, margin and outside pilose, margin with few glands, inside glabrous; 2 outer smaller ones 1-1.3 by 0.8-1 mm; 3 inner larger ones 1.4-2.2 by 1.1-1.5 mm, margin petaloid. Petals 5, obovate, 0.7-1 by c. 0.3 mm, white; claw 0-0.3 mm high; margin and less so outside and inside hirsute, apex acute; scales 0.6-0.7 mm long, free, apex not broadened; crest absent.
