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.

Leaf: generally basal, odd-1-pinnately, 1-palmately, or 1-ternately compound; leaflets 1–8(13) per side, ± toothed, generally ± separated, terminal generally ± = lateral; margins generally flat. Inflorescence: generally cyme, generally ± open; pedicels generally ± straight, bractlets 0. Flower: hypanthium ± shallow, bractlets generally 5, generally < sepals, generally flat; sepals ± triangular; petals (2)4–20 mm, >= sepals, generally ± widely obcordate, generally yellow; stamens 10–25; pistils generally > 10, ovaries superior, styles slender to ± tapering, generally attached near fruit tip. Fruit: achene, generally glabrous.Key to Potentilla
± 400 species: mostly northern temperate, arctic. (Latin: diminutive of powerful, for reputed medicinal value) Other taxa in TJM (1993) moved to Comarum, Dasiphora, Drymocallis.
Plant tufted from stolons, nonglandular. Leaf: palmate; 2–12 cm, leaflets 3–5, central generally 10–25 mm, wedge-shaped to obovate, distally 7–11-toothed ± 1/4 to midvein, sparsely strigose. Inflorescence: flowers 1 from stolon nodes; pedicels 2–8 cm. Flower: hypanthium 2–4 mm wide; sepals 4; petals 4, 3–8 mm; filaments 2–3.5 mm, anthers ± 1 mm; pistils 4–20, styles ± 1.5 mm, slender.
