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.

Perennial herb from thick caudex or elongate rhizome. Stem: ascending to erect, generally hairy. Leaf: generally basal, generally odd-1-pinnately compound, upper cauline simple or not; leaflets lobed, alternately large, small, teeth uneven. Inflorescence: generally cyme, open; pedicel bractlets 0. Flower: hypanthium shallow, bractlets generally 5; stamens > 20; pistils many, ovary superior, continuous to style. Fruit: achene, ovoid to fusiform, ± flat; style elongated, persistent.Key to Geum
40–50 species: generally northern temperate, arctic. (Latin: ancient name)
