Flowers 1– 2 (–3) per leaf axil; peduncle and pedicel combined 0.6–2.8 cm long, the articulation about one-third to half-way from peduncle base, stellate-hairy; epicalyx segments 7–9, linear to linear-elliptic, 0.7–1.2 cm long, free to base, stellate-hairy; calyx narrowly ovoid, 5-lobed (2 or 3 lobes sometimes tardily separating from the adjacent lobe), 1–2 cm long, the lobes 0.3–0.6 cm long, stellate-hairy; petals 5, imbricate, adnate to the ovary/staminal column for c. 0.3 cm but otherwise free, spathulate with the apex obliquely truncate, 2.2–3.7 cm long, deep rose pink, wine-red or red, stellate-hairy on the abaxial surface; staminal column 2.4–3.2 cm long, white, 5-toothed at the apex, stellate-hairy proximally and glandular-hairy for the remainder (especially so on the apical teeth), stamens 20, in a whorl of 10 pairs (the stamens of each pair superposed), the whorl 0.2–0.3 cm below the apex of the staminal column, the filaments spreading-ascending, 0.3–0.6 cm long, white; style branches 5, erect and appressed to each other at anthesis and later separating, elongating and recurving, 0.3–0.8 cm long, very pale pink, the stigmas capitate, hairy; ovary conical, 0.5 cm long, stellate-hairy, 5-loculate with c. 6 ovules per locule.
