Belongs within: Ranunculaceae.

Delphinium is a genus of perennial herbs bearing bilateral flowers with the upper sepals spurred. Many species are highly toxic and cause numerous deaths in livestock (Hickman 1993).

Characters (from Hickman 1993): Perennial; root generally <10 cm, more or less fibrous or fleshy; buds generally obscure. Stem generally 1, erect, generally unbranched; base generally more or less as wide as root, generally firmly attached to root, generally more or less reddish or purplish. Leaves simple, basal and cauline, petioled; blades generally palmately lobed, deep lobes generally 3–5, generally <6 mm wide, generally also lobed; lower leaves generally dry, often absent in flower; cauline merging into bracts upward. Inflorescence a raceme or somewhat branched, terminal; flowers generally 10–25; pedicels generally more or less spreading. Flower bilateral; sepals 5, petal-like, generally spreading, generally more or less dark blue, uppermost spurred; petals 4, smaller than sepals, upper 2 with nectar-secreting spurs enclosed in uppermost sepal, lower 2 clawed, with blades generally 4–8 mm, notched, generally more or less perpendicular to claws, generally colored like sepals, generally obviously hairy; pistils 3(–5). Fruit an aggregate of 3(–5) erect follicles, generally 2.5-4x longer than wide. Seed dark brown to black, often appearing white, generally winged when immature, generally without inflated collar; coat cell margins generally straight.
