Flowers solitary, axillary; pedicels 2–6 cm long; calyx lobes 7–11 mm long, elongating to 15 mm in fruit, long-acuminate, densely hirsute or bristly; petals usually pale purple, whitish at the base, 8–12 mm long. Fruit transversely elliptic, 10–20 mm diam., remaining on the widely spreading calyx; mericarps 9–20, bristly or hirsute, beaked dorsally. Flowers mostly summer.
