Flowers 4-merous, borne in pedunculate 20–100-flowered corymbs 2–6 cm. across; peduncles 0.3–2 cm. long, glabrescent to pubescent; pedicels 2–9 mm. long, adpressed pubescent; bracteoles inconspicuous.. Calyx-tube 0.75– 1 mm. long, glabrous to pubescent; calyx-limb 0.25–1.25 mm. long, shorter or longer than the tube, and often wider, truncate to repand, glabrous to pubescent outside and inside.. Corolla whitish; tube 2–3 mm. long, with a ring of deflexed hairs above mid-point inside, and pubescent at throat; lobes oblong-ovate, 1.5–2.5 mm. long, 1.25–1.5 mm. wide, obtuse to acute.. Anthers reflexed.. Style up to 8 mm. long; stigmatic knob cylindrical, (0.5–)0.75–1 mm. long.. Disk pubescent.. Fruit black when mature, almost didymous, 5–8 mm. long, 8–14 mm. wide; pyrene 3/4-circular in outline, 5–8 mm. wide, with a groove extending from point of attachment, on either side, to lateral face, perpendicular (in 1-seeded fruit) or angled upwards (2-seeded fruit), cartilaginous, slightly bullate.
