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 to perennial herb, occasionally from stolons or caudices, terrestrial or aquatic; roots generally fibrous. Stem: prostrate to erect. Leaf: basal, cauline, or both, alternate, generally reduced upward; petiole base flat, stipule-like or not; basal, proximal cauline petioles generally long; blades simple to dissected or compound, entire to toothed. Inflorescence: cyme, axillary or terminal, 1–few-flowered. Flower: sepals 3–5(6), generally early-deciduous, generally green to yellow or purple; petals 0–17[(150)], shiny, generally yellow, occasionally white or purple, nectaries near base, pocket-like or with flap-like scale; anthers yellow; pistils generally many. Fruit: achene, compressed or not, ± spheric, disk-like (width 3–15 × depth), or lenticular (width 1–2 × depth), beaked.Key to Ranunculus
± 300 species: worldwide except lowland tropics; some ornamental. (Latin: small frog, from wet habitats)
Unabridged etymology: (Latin: diminutive of Rana, frog, from wet habitats)
Perennial herb 8–18 cm, erect from short caudex, not rooting at nodes. Leaf: basal, 1.5–3.8 cm, 2.1–3.8 cm wide, cordate, 1–2-ternate, leaflets 2–3 × parted, ultimate segments elliptic to linear, margins entire or few-toothed, tips obtuse to acuminate; cauline 0 or ± like, << basal, ± sessile. Flower: receptacle bristly; sepals 5, spreading, 9–15 mm, 5–9 mm wide, persistent in fruit; petals 5, 12–18 mm, 9–13 mm wide, ± pink-white. Fruit: body 6–12 mm, 4–6 mm wide, wall inflated, papery, longitudinal veins strong, beak 0.2–0.6 mm, deltate or awl-shaped from a deltate base.
