Annual to tree, glandular or not. Leaf: simple to palmately or pinnately compound, generally alternate; stipules free to fused (0), persistent to deciduous. Inflorescence: cyme, raceme, panicle, cluster, or flowers 1; bractlets on pedicel ("pedicel bractlets") generally 0–3(many), subtended by bract or generally not. Flower: generally bisexual, radial; hypanthium free or fused to ovary, saucer- to funnel-shaped, subtending bractlets ("hypanthium bractlets") 0–5, alternate sepals; sepals generally 5; petals generally 5, free; stamens (0,1)5–many, anther pollen sacs generally 2; pistils (0)1–many, simple or compound, ovary superior to inferior, styles 1–5. Fruit: 1–many per flower, achene (fleshy-coated or not), follicle, drupe, or pome with generally papery core, occasionally drupe-like with 1–5 stones. Seed: generally 1–5 (per fruit, not per flower).
110 genera, ± 3000 species: worldwide, especially temperate; many cultivated for ornamental, fruit, especially Cotoneaster, Fragaria, Malus, Prunus, Pyracantha, Rosa, Rubus. [Potter et al. 2007 Plant Syst Evol 266:5–43] Number of teeth is per leaf or leaflet, not per side of leaf or leaflet, except in Drymocallis. —Scientific Editors: Daniel Potter, Thomas J. Rosatti.

Shrub, small tree, 1–6 m; dioecious (monoecious). Leaf: simple, deciduous, 5–13 cm, 2–5 cm wide, elliptic to narrow-obovate, abaxially paler, sometimes puberulent becoming glabrous, adaxially glabrous; margins generally entire, ± rolled under; stipules early-deciduous; petiole 5–15 mm. Inflorescence: racemes on short lateral branches, 3–10 cm, pendent, bracted; pedicel bractlets 1–2, near top. Flower: fragrant, unisexual, occasionally bisexual; hypanthium 3–4.5 mm, bractlets 0; petals 3–6 mm, clawed, white. Staminate flower: hypanthium persistent; petals > pistillate petals; stamens 15, in 3 series, prominent. Pistillate flower: most of hypanthium deciduous after flower; ovaries generally 5, prominent, free, styles deciduous. Fruit: drupes 1–5, 5–15 mm, bean-shaped, blue-black, glaucous.
