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, 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 5–25 cm, erect or decumbent, not bulbous-based; roots basal, not tuberous. Leaf: segment tips rounded; distal cauline much-reduced, deeply parted or compound. Flower: receptacle glabrous or sparsely long-hairy; sepals 5, spreading, 4–8 mm, 2–6 mm wide, early-deciduous; petals 5–8, 6–13 mm, 4–13 mm wide. Fruit: body 1.4–2 mm, 1–1.6 mm wide, lenticular, wall thick, smooth, beak 0.6–1.8 mm, straight but occasionally curved in youth, lanceolate or awl-shaped. [Online Interchange]
Unabridged note: 2 other varieties, not in California.
Stem: caudex 2.5–4.5 cm, persistent leaf bases many. Leaf: basal 1.5–1.5 cm, 0.8–2 cm wide, reniform, shallowly 5–9-lobed or occasionally 3-parted, lateral segment again lobed, base truncate, middle segment unlobed, ultimate segments rounded or obtuse.
Open, rocky alpine slopes, meadows; 2700–4300 m. High Sierra Nevada, San Bernardino Mountains, San Jacinto Mountains, Warner Mountains, East of Sierra Nevada (Sweetwater, White mtns); Nevada. Jul–Sep [Online Interchange]
