Plants 50–150(–300) dm. Branches grayish brown or dark reddish brown, glabrous; short shoots of young plants often thorn-tipped. Leaves: petiole 1.5–5 cm, slightly pubescent when young; blade ovate or suborbiculate to elliptic, 2–5(–7) × 1.5–2.5 cm, base broadly cuneate to almost rounded, margins obtusely serrate, serrulate, or crenulate, sometimes entire, ?densely ciliate when young?, apex acute or shortly acuminate, surfaces pubescent when young, glabrescent. Pedicels 2–3.5 cm, pubescent or glabrate. Flowers 25–35 mm diam.; sepals triangular-lanceolate, 5–9 × 3–4 mm, apex acuminate; petals white, obovate, (12–)13–15 × 10–13 mm; ovaries 5-locular; styles (3–)5. Pomes green, yellowish, or reddish green, globose, subglobose, ovoid, or pyriform, 30–160 × 15–120 mm; sepals persistent. 2n = 34.
A medium to large tree. It grows to 20 m tall. It often has suckers around the base. It loses its leaves during the year. The leaves have stalks. The leaves are 5-14 cm long by 4-9 cm wide. They are oval to sword shaped. They taper to the tip. They have fine teeth around the edge. They are glossy and dark green above. The flowers are white. They occur in short shoots at the ends of branches. The fruit is pear shaped. It is rough with close, raised specks. They are yellowish green when ripe. The pulp is gritty. The thorns have been bread out of cultivated pears. There are many named varieties.

Flowers: in umbel-like racemes or corymbs; calyx with tube turbinate or globose, accrescent; petals 5, broadly oblong or obovate, white; Sep., Oct. Fruit a pome, ± turbinate, up to ± 10 mm long, mesocarp fleshy-juicy with grit cells; seeds black or brownish black.
Pyramidal tree to 15 m; lvs elliptic to subrotund, finely and rather bluntly serrulate, involute in bud, glabrous at maturity; fls white, 2.5–3 cm wide; hypanthium nearly closed by a ring of tissue at the summit, surrounding the free styles; anthers red; cal persistent; fr pyriform to obovoid, 6–15 cm, containing stone-cells; 2n=34.
