Flowers? heterostylous, 5-merous, in branched panicles, each component rather dense, ± 1 cm. long; peduncle 6 cm. long; secondary branches 0.5–1.2 cm. long; bracts ± triangular, distinctly ciliate.. Calyx-tube subglobose, 1 mm. long, glabrous; limb 1 mm. long; lobes oblong or triangular, 0.6–1 mm. long, ciliate; disc prominent.. Corolla white; tube 4 mm. long; lobes ovate-elliptic, 2 mm. long, 1.2 mm. wide, acuminate.. Stamens with filaments 1 mm. long in short-styled flowers.. Style 1.2 mm. long in short-styled flowers; stigma-lobes ellipsoid, 0.4 mm. long..
