Inflorescences terminal, corymbose, 4–6 cm, several flowered, sometimes axillary and 1-or 2-flowered; bracts brownish, ovate-lanceolate to ovate, 0.8–1.6 cm × 5–10 mm, glabrous.

Calyx purplish red, abaxially glabrous or hairy; sepals erect, rarely reflexed in fruit, broadly ovate, 1.2–1.8 cm × 6–10 mm, inner sepals with margin gray tomentose, apex acuminate. Petals red, suborbicular, 6–9 mm in diam., shorter than sepals, base narrowly clawed, margin erose or coarsely dentate. Stamens somewhat shorter than petals. Pistils many; apical part of ovary and basal part of style densely gray or grayish yellow long tomentose. Aggregate fruit red, globose, 1.5–2 cm in diam., densely long tomentose or not and soft hairy, with persistent styles. Fl. May–Jun, fr. Jul–Aug.
