Flowers blooming at leaf emergence; hypanthium campanulate, 3–4 mm, usually glabrous, rarely puberulent externally; sepals spreading, triangular, 1.5–2.5 mm, margins sparsely glandular-toothed, ciliate, surfaces glabrate; petals usually dark-pink, sometimes nearly white, elliptic, obovate, or suborbiculate, (5–) 8–11 mm; ovaries hairy. Drupes greenish yellow to red-orange, globose to asymmetrically obovoid, compressed, 10–18 mm, base cuneate-stipitate, apex mucronate, densely puberulent; hypanthium persistent; mesocarps leathery to dry (often splitting); stones ellipsoid to subglobose, ± flattened.
