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
Perennial herb, generally ± glandular, generally resinous-smelling; caudex generally branched. Stem: generally ascending to erect. Leaf: generally basal, odd-1-pinnately compound, generally ± flat; cauline alternate, reduced upward; leaflets 2–15 per side, uppermost lateral generally ± fused with terminal. Inflorescence: cyme; pedicels generally straight, bractlets 0. Flower: hypanthium cup-like, ± flat-bottomed, width ± 2 × length, bractlets 5, generally 2/3 sepals; sepals often reflexed; petals generally ± = sepal, blunt, white; stamens 10, filaments ± flat, often forming a tube; pistils 2–many, ovary superior, style attached below fruit tip, ± thicker at base. Fruit: achene.Key to Horkelia
20 species: western North America. (J. Horkel, German plant physiologist, 1769–1846) [Ertter & Reveal 2007 Novon 17:315–325] Many attractive to bees; data apply to basal leaves, pressed hypanthia.
Plant generally tufted (± matted), green to ± gray. Stem: generally 10–60 cm. Leaf: stipules entire. Inflorescence: clusters 1–several, generally ± head-like; pedicels generally 1–3 mm. Flower: hypanthium width generally 2–3.5 mm, ± 1–2 × length, bractlets < 0.5 mm wide, linear; sepals generally 2–3 mm; petals ± wedge-shaped; filament base 0.2–1 mm wide; pistils generally 10–20.
