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
Perennial herb; root generally < 10 cm, ± fibrous or fleshy; rootstock buds in life generally obscure (0 or obscure on herbarium specimens). Stem: erect, generally 1, generally unbranched; base generally ± as wide as, generally firmly attached to root, generally ± red or purple. Leaf: simple, basal and cauline, petioled; blades generally palmately lobed, deep lobes generally 3–5, generally < 6 mm wide, generally also lobed; cauline proximal generally dry, generally 0 in flower, distal merging into bracts. Inflorescence: raceme or ± branched, terminal; flowers generally 10–25; pedicels generally ± spreading. Flower: bilateral; sepals 5, petal-like, generally spreading, generally ± dark blue, uppermost spurred; petals 4, << sepals, upper 2 with nectar-secreting spurs enclosed in uppermost sepal, lower 2 clawed, with blades (limbs) generally 4–8 mm, 2-lobed, generally ± perpendicular to claws, generally colored like sepals, generally obviously hairy especially on lobes proximally; pistils 3(5). Fruit: follicles 3(5), erect, length generally 2.5–4 × width. Seed: generally winged in youth, collar inflated at widest end or generally not, dark brown to black, generally appearing white; coat cell margins generally straight.Key to Delphinium
± 300 species: arctic, northern temperate, subtropics, tropical mountains worldwide; 3 commonly cultivated as ornamental in North America. (Latin: dolphin, from bud shape) Most species highly TOXIC, attractive to, killing many cattle, fewer horses, sheep. Hybrids common, especially in disturbed places. Root length is of coarse parts only.

Root generally > 15 cm, distally branched. Stem: 30–270 cm, base equal in width or occasionally narrower than root, firmly attached, generally curly-puberulent. Leaf: basal present in flower or not, ± glabrous; lobes 5–27. Inflorescence: pedicels 15–55 mm, (6)15–80 mm apart, puberulent. Flower: sepals generally ± forward-pointing, red, lateral 11–15 mm, spur 15–24 mm; lower petals flattened, blades 4–5 mm, with hairs few, short, yellow, obscure to naked eye. Fruit: 12–18 mm, ± straight. Seed: bumpy.
2n=16. Slopes, generally talus, chaparral; 300–1500 m. South Coast Ranges, Southwestern California, w edge Sonoran Desert; Baja California. Hybridizes with Delphinium parryi (Delphinium ×inflexum Davidson). Generally hummingbird-pollinated. Feb–Jul [Online Interchange]
