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, hairs short, simple, nonglandular and/or long, cross-walled, glandular.Key to Drymocallis
Stem: ± erect, from ± branched caudex or rhizomes.
Leaf: basal and cauline, alternate, odd-1-pinnately compound; leaflets toothed, terminal generally >= lateral.
Inflorescence: cyme, ± open; pedicels straight, bractlets 0.
Flower: hypanthium ± shallow, bractlets 5; sepals ± triangular; petals < to > sepals, white to yellow; stamens generally 20–25, pollen sac 1, horseshoe-shaped; pistils many, styles fusiform, attached below fruit middle.
Fruit: achene, glabrous.
30 species: n temperate. (Greek: wood beauty) [Ertter 2007 J Bot Res Inst Texas 1:31–46] Recognition based on morphological, molecular evidence. Drymocallis ashlandica (Green) Rydb. (inflorescence narrow, petioles glandular, petals yellow) in sw OR, possibly nw CA.
Unabridged note: Convergence of morphological, molecular evidence mandates recognition of Drymocallis; infrageneric taxonomy provisional. Key characters include relative proportions of 2 hair types: short simple nonglandular hairs and longer cross-walled glandular hairs.
Stem: generally 10–60 cm.
Leaf: basal generally 5–20 cm, sheathing base generally glabrous, lateral leaflet pairs generally 3–4, terminal leaflet generally 10–40 mm, ± obovate, ± obtuse, teeth ± single, generally 4–10 per side.
Inflorescence: not leafy; pedicels 2–10 mm, lowermost to 30 mm, glandular hairs generally 0–few, short nonglandular hairs generally dense.
Flower: opening widely; hypanthium bractlets lance- linear, 2–5 mm, 0.5–1 mm wide; sepals 3–8 mm, ± acute; petals spreading, generally 4–8 mm, > sepals, widely obovate; style generally ± 1 mm.
Fruit: ± 1 mm, brown. [Online Interchange]
Unabridged note: Drymocallis ashlandica (Greene) Rydb. (inflorescence narrow, petioles glandular, petals yellow) on Mt. Ashland, OR.
Stem: glandular hairs present at base or not.
Inflorescence: spreading, branch angle generally 20–40°.
Flower: petals generally ± yellow.
Generally ± moist, often rocky places; 900–2600 m. Northwestern California, Cascade Range, n High Sierra Nevada, Modoc Plateau;
