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.

Key to Rosaceae
Shrub, small tree. Stem: bark gray- to red-brown; overwintering buds ovate to lanceolate, ± red to ± purple. Leaf: simple, deciduous; stipules deciduous. Inflorescence: raceme, cluster (panicle), flowers 3–16+; pedicel bractlets generally 1–2. Flower: hypanthium bell- to urn-shaped, bractlets 0; sepals persistent; petals erect to spreading, white (suffused with red); stamens ± 10–20; ovary inferior, 2–5-chambered, styles 2–5. Fruit: pome of 2–5 papery segments, berry-like, generally spheric, generally blue-black.Key to Amelanchier
± 25 species: temperate North America, Eurasia, northern Africa. (Latin: from old French common name) Fruit of some species used by Native Americans for food.

Unabridged note: Variation in Amelanchier in western North America not studied as extensively as in eastern North America, where hybridization, polyploidy, and apomixis have contributed to considerable taxonomic complexity (Campbell & Wright 1996 Folia Geobot Phytotax 31:345–354; http://biology.umaine.edu/Amelanchier).
