Trees, not suckering, 50–100 dm, not thorny. Twigs with axillary end buds, glabrous. Leaves deciduous; petiole (12–) 20–45 mm, glabrous, glandular distally or on margins at bases of blades, glands 1–5; blade broadly ovate to suborbiculate, (3–) 5–9 × (2–) 4–8 cm, base usually obtuse to rounded, sometimes truncate or subcordate, margins singly to doubly crenate-serrate, teeth blunt, glandular, apex abruptly short-acuminate, abaxial surface with tufts of hairs in vein-axils, adaxial glabrous. Inflorescences solitary flowers. Pedicels 1–3 mm, hairy. Flowers blooming before leaf emergence; hypanthium tubular-campanulate, 4–6 mm, glabrous or sparsely hairy externally; sepals reflexed, oblong-ovate, 4–6 mm, margins remotely glandular-toothed, surfaces sparsely hairy; petals white (pink in bud), broadly elliptic to suborbiculate, 8–12 mm; ovaries hairy. Drupes yellow to orange, often tinged with red, ellipsoid to globose, laterally compressed, 25–60 mm, velutinous; mesocarps fleshy; stones ellipsoid to subglobose, strongly flattened, not pitted. 2n = 16.
