Inflorescences terminal or axillary, paniculate, 10–40 cm; rachis and pedicels shortly ferrugineous tomentose, later glabrescent; bracts scaly. Sepals 5, lanceolate to ovate, ca. 3 mm, sparsely and shortly ferrugineous tomentose abaxially, apex acuminate. Petals 5, milky yellow, oblong, 5–7 mm, shortly ferrugineous tomentose abaxially, pilose adaxially, apex obtuse. Stamens ca. 10, all fertile. Carpel 1, nearly as long as long stamens, densely pubescent. Follicle long ellipsoid, slightly inflated, 3–3.5 × 1.5–2 cm, base gradually narrowed into a short, slender stipe, apex shortly beaked and slightly oblique; pericarp bright red, woody, glabrous abaxially, slightly pubescent adaxially, longitudinally striate.
