Daniel Potter & Barbara Ertter, family description, key to genera; treatment of genera by Daniel Potter, except as noted

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


Genevieve J. Kline

Perennial herb, finely glandular. Stem: 1–several, erect, rhizomed. Leaf: odd–1-pinnate; leaflets evenly toothed, generally alternately large, small. Inflorescence: spike-like raceme, terminal, often also axillary; pedicel bractlets 2, near tip, fused at base. Flower: hypanthium stalk 1–2 mm, reflexed in fruit, bractlets 0; petals ± elliptic to ± obovate [or otherwise], yellow; stamens 5–15; pistils 2, ovary superior, continuous to style at top. Fruit: hypanthium obconic to cup-shaped, hard, ridged, rim with 3–5 rows of spreading hooked bristles; sepal tips converged inward, with hypanthium generally encasing 1 achene.
± 20 species: generally northern temperate, South Africa, Brazil, Argentina. (Greek: eye disease, from former use as cure) [Kline & Sorensen 2008 Brittonia 60:11–33]

Key to Agrimonia

Stem: generally 20–150 cm; glands short-stalked, also larger, dot-like above. Leaf: largest generally 12–21 cm; stipules 0.5–3 cm, ± sickle-shaped to half-ovate; major leaflets 3–11, 1–11 cm, ± diamond-shaped to elliptic; abaxially with soft, shaggy and coarse, straight nonglandular hairs, stalked and dot-like glands. Inflorescence: generally 8–60 cm, generally 10–60-flowered; pedicels generally 3–6 mm. Flower: sepals 1–3 mm, tips often long-tapered; petal 2–4 mm. Fruit: hypanthium 2–7 mm; bristles 3–4 mm, in 3 rows, lowermost spread ± 90° (pressed upward on dried specimens); converged sepal tips not hooked.
2n=56. Moist places, generally in woodland; 1000–3000 m. San Bernardino Mountains (Oak Glen), White and Inyo Mountains (White Mtns); to eastern North America, mountains of Mexico. [Agrimonia brittoniana Bicknell; Agrimonia striata var. campanulata Fernald] Jun–Aug [Online Interchange]
