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
Annual, short-lived, generally tufted. Leaf: basal, simple, linear. Inflorescence: scapose, 1-flowered. Flower: sepals (3)5(8), 1.5–4 mm, alike, free, green or scarious-margined, spurred; petals 0–5, free, linear to narrowly spoon-shaped, long-clawed, white; stamens 5–25; pistils 10–400, 1–2.5 mm, ovules 1, styles thread-like. Fruit: achene, angled, wall not veined, styles persistent, ± enlarged in fruit; receptacle elongate, generally growing and producing ovules after flower.Key to Myosurus
