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 to vine, often thicket-forming, generally prickly. Leaf: generally odd-pinnately compound; stipules generally attached to petiole, generally gland-margined. Inflorescence: generally ± cyme or flowers 1; pedicel bractlets 0. Flower: hypanthium urn-shaped, bractlets 0; sepals often with long expanded tip; petals generally 5 (except cultivated), generally pink in California (white to red or yellow); stamens generally > 20; pistils generally many, ovaries superior, styles attached at tip, generally hairy. Fruit: bony achenes generally enclosed in fleshy, generally ± red hypanthium (hip).Key to Rosa
100+ species: generally northern temperate. (Latin: ancient name) [Ertter & Lewis 2008 Madroño 55:170–177] Species hybridize freely; other non-natives established locally. FNANM treatment by Lewis & Ertter uses both subspecies, varieties, the latter mostly reserved for localized variants within a subsp.; 2 vars. in Rosa woodsii subsp. gratissima treated here but not in TJM2 (2012).

Shrub or thicket-forming, 8–30 dm. Stem: prickles generally few, generally not paired, ± 5–15 mm, thick-based, compressed, curved. Leaf: axis ± hairy, hairs 0.2–1 mm, glandular; leaflets generally 5–7, ± hairy, glandular; terminal leaflet generally 10–35 mm, elliptic to ± widely obovate, widest near middle, tip obtuse, margins double-toothed, glandular. Inflorescence: generally 1–8-flowered; pedicels ± 10 mm, glabrous, stalked-glandular. Flower: hypanthium generally 4–5 mm wide at flower, ± glabrous, glandless to sparsely stalked-glandular, neck ± 3 mm wide; sepals glandular, lateral lobes toothed, tip ± = body, generally toothed; petals generally 10–20 mm, pink; pistils 20–45. Fruit: 10–18 mm wide; ± ellipsoid; sepals spreading to reflexed, unevenly deciduous; achenes 4–5 mm.
