Flowers heterostylous, 5-merous, in much-branched panicles 2.5–6 cm. long; peduncles 0.5–3 cm. long, glabrous or shortly pubescent; branches 0.3–1.2 cm. long, shortly sparsely pubescent; pedicels short or ± 1–2 mm. long, very shortly pubescent or tomentose; main bracts ovate, 2–3 mm. long, clasping the stem, rest small, often apically ciliate.. Calyx-tube rounded-conical, 0.5–1 mm. long, glabrous or tomentose; limb campanulate to tubular, 2–3 mm. long, glabrous, often split for ± 1 mm.; lobes obtusely triangular, ± 0.5–1 mm. long, often ciliate on the apical margins.. Corolla white or cream or reddish in bud, glabrous outside; tube 4–5 mm. long; lobes oblong-elliptic to ovate, 2 mm. long, 1–1.8 mm. wide, ± uncinate at the apex.. Stamens with filaments ± 0.3 mm. long in short-styled flowers.. Style 2.5–3 mm. long in short-styled flowers, 4.5 mm. long in long-styled flowers; stigma-lobes ± 0.5 mm. long.. Drupes orange-red, with 2 pyrenes, subglobose or ellipsoid, 5–7 mm. long and wide, glabrous, grooved, crowned with the calyx-limb; pyrenes pale brown, semi-globose, 6 mm. long, 5–5.5 mm. wide, 2.5 mm. thick, dorsally 6-grooved..
