Inflorescence axillary and terminal, lax, glabrous, 5.5-8.7 cm long; peduncle 2.7-4.2 cm by 1-1.2 mm; bracts and bracteoles small, deltoid, mostly with two small opposite bracteoles on the pedicel (possibly empty bracts) and a single bracteole immediately beneath the calyx; pedicels 6-13.5 mm long (including area below opposite bracteoles). Sepals ovate, 2-2.2 by 1.1-1.3 mm, 1.7-1.8 times as long as wide, apex obtuse to rounded, ciliate at apex, otherwise glabrous. Corolla whitish; tube 6.3 mm long, 1.4 times as long as lobes; lobes c. 4.4 by 1.9 mm, 2.3 times as long as wide; glabrous outside, densely pubescent around and above the stamens inside. Stamens inserted at c. 1.5 mm from corolla base which is 0.24 of tube length; filaments c. 0.3 mm long; anthers c. 1.5 by 0.5 mm. Disk irregularly deltoid, c. 0.3 mm long. Ovaries c. 0.5 mm long, glabrous; style and style head c. 2 mm long. Fruit unknown.
