This text currently parallels The Jepson Manual: Vascular Plants of California, Second Edition that is now available at the University of California Press.
Text appearing in blue on this page will not appear in the printed book; it will be displayed only on the Web. Specimen numbers are hyperlinked to records in the Consortium of California Herbaria data view where possible. Taxa are hyperlinked to entries in the Jepson Interchange via the "[Online Interchange]" link.
Perennial; 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)
