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; flowers generally nodding. 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)
