RANUNCULACEAE BUTTERCUP FAMILY

Margriet Wetherwax & Dieter H. Wilken, family description, key to genera

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.

AQUILEGIA COLUMBINE

Justen Whittall, Scott A. Hodges & Dieter H. Wilken

Perennial herb; caudex thick, branched to not. Stem: 1–few, ascending to erect, branched to not, scapose to not, glabrous to glandular-hairy. Leaf: basal 1–3-ternate, petiole generally long; cauline 0–few, generally much reduced, deeply 3-lobed to 1–2-ternate, petiole short to ± 0; segments generally wedge-shaped to obovate, abaxially pale green to glaucous, adaxially green to gray, glabrous to glandular. Inflorescence: few-flowered raceme or flower 1, terminal; axis, pedicels glabrous to glandular; flower buds generally pendent. Flower: sepals 5, petal-like, spreading [to ± reflexed]; petals 5, spurs between sepals, mouths < to > 90° to exposed filaments; pistils generally 5. Fruit: follicle, glabrous to glandular. Seed: smooth, shiny, brown to black.
± 70 species: temperate North America, Eurasia. Many species, hybrids cultivated as ornamental; natural hybrids common; recent adaptive radiation with specialized pollinations syndromes (bee, hummingbird, hawkmoth).
Unabridged etymology: (Perhaps Latin: eagle, from spurs, or water-drawer, from habitats)
