Flowers ?functionally unisexual or monoecious, plants dioecious?, 3–5 cm diam.; hypanthium ovoid, 4–6 × 4–5 mm, stipitate-glandular; sepals narrowly to broadly ovate-lanceolate, 10–18 × 2–4 mm, margins entire, tip 3–4 × 0.5–1 mm, abaxial surfaces pubescent, stipitate-glandular; petals single, rose-purple to pink, fading to white, 18–25 × 16–25 mm; ?stamens 212?; carpels 20–25, styles glabrous, exsert 5–6 mm beyond stylar orifice rims (0.5 mm diam.), hypanthial disc 2–3 mm diam. Hips bright red, subglobose to globose, 6–10 × 6–9 mm, ?firm?, sparsely stipitate-glandular ?often undeveloped because of dioecy, then early deciduous?. Achenes 17–22, fawn, 4–5 × 2.5–3 mm. 2n = 14.
