Petals 3–8, obovate-oblong, 1.2–2.2 cm × 4–8 mm, fleshy, abaxially glabrous, adaxially usually pubescent, base saccate, margin entire, irregularly denticulate or erose in upper part, apex rounded. Stamens usually 10; filaments 1–1.5 cm, pubescent; anthers yellowish, short, appearing peltate, to 2 mm in diam.; sacs connate, opening by a distal slit. Ovary essentially glabrous, grooved along sides where capsule segments separate; placenta axile; style 2–3 mm, shorter than ovary, thick, articulation between style and ovary conspicuous; stigma yellow-brown, ca. 4 mm in diam., funnelform, glabrous.
