Annual, perennial herb, woody vine [shrub], occasionally aquatic. Leaf: generally basal and cauline, alternate or opposite, simple or compound; petioles at base generally flat, occasionally sheathing or stipule-like. Inflorescence: cyme, raceme, panicle, or flowers 1. Flower: generally bisexual, generally radial; sepals 3–6(20), free, early-deciduous or withering in fruit, generally green; petals 0–many, generally free; stamens generally 5–many, staminodes generally 0; pistils 1–many, ovary superior, chamber 1, style 0–1, generally ± persistent as beak, ovules 1–many. Fruit: achene, follicle, berry, ± utricle in Trautvetteria, in aggregate or not, 1–many-seeded.
± 60 genera, 1700 species: worldwide, especially northern temperate, tropical mountains; many ornamental (Adonis, Aquilegia, Clematis, Consolida, Delphinium, Helleborus, Nigella). some highly TOXIC (Aconitum, Actaea, Delphinium, Ranunculus). [Whittemore & Parfitt 1997 FNANM 3:85–271] Taxa of Isopyrum in TJM (1993) moved to Enemion; Kumlienia moved to Ranunculus. —Scientific Editors: Douglas H. Goldman, Bruce G. Baldwin.
Key to Ranunculaceae
Perennial herb from caudex, rhizome, or tuber.

Inflorescence: terminal, flowers 1 or 2–7 in cymes; peduncle erect; pedicel elongated in fruit; involucre bracts sessile or stalked, generally in 1–2 whorls of 2–5, simple to compound, ± like leaves or leaflets in size, shape. Flower: receptacle elongated in fruit; sepals 5–10, petal-like; petals generally 0; stamens 10–200; pistils many, styles persistent as beaks. Fruit: achene.Key to Anemone
