A deciduous tree growing to 15–20 m (rarely to 30 m) tall with a trunk up to 1 m diameter, though can also be a shrub 2–3 m tall on exposed sites. The bark is brown, smooth on young trees, becoming fissured and flaky on old trees. The winter buds are green, with a sticky resinous coating. The leaves are 15–25 cm long, pinnate with 13-21 leaflets 3–6 cm long and 1 cm broad, with a bluntly acute apex, and a serrated margin on the outer half or two thirds of the leaflet. The flowers are 13–18 mm diameter, with five white petals and 20 creamy-white stamens; they are produced in corymbs 10–14 cm diameter in late spring, and are hermaphrodite and insect pollinated. The fruit is a pome 2–3 cm long, greenish-brown, often tinged red on the side exposed to sunlight; it can be either apple-shaped or pear shaped.
