Shrubs to 1 m tall, with slender thorns. Branches spreading; branchlets purple when young, blackish brown when old, terete, scabrous and tomentose when young, verruculose, and glabrous when old; buds purple, triangular-ovate, glabrous, apex acute. Stipules reniform, ca. 1 cm, herbaceous, glabrous, margin serrate, apex obtuse; petiole ca. 5 mm, glabrous; leaf blade obovate or spatulate to broadly ovate, 3–5 × 2–3 cm, glabrous, base cuneate or broadly cuneate, margin crenate, apex obtuse or acute. Pedicel short or nearly absent, glabrous. Flowers 3–5-fascicled, 2.5–4 cm in diam. Hypanthium campanulate, abaxially glabrous. Sepals ovate, rarely suborbicular, 4–5 mm, abaxially glabrous, adaxially and margin brown pubescent. Petals dark red, obovate or suborbicular. Stamens 40–60, ca. 1/2 as long as petals. Styles ca. as long as stamens, connate at base, glabrous. Pome yellow, subglobose, 3–4 cm in diam.; sepals caducous; fruiting pedicel short or nearly absent. Fl. Mar–Jun, fr. Aug–Oct.
Shrubs, 0.2–10 dm. Branches purple, scabrous (and tomentose when young, becoming blackish brown, verrucose, glabrous with age).

Flowers 25–40 mm diam.; sepals ovate, rarely suborbiculate, 4–5 mm; petals dark red, obovate or suborbiculate, 15–25 mm; stamens 40–60, 1/2 length of petals. Pomes yellow, subglobose, 23–40 mm diam.
