Lincoln Constance & Margriet Wetherwax, except as noted

Annual to perennial herb [shrub, tree], generally from taproot. Stem: generally ± scapose, generally ribbed, hollow. Leaf: basal and generally cauline, generally alternate; stipules generally 0; petiole base generally sheathing stem; blade generally much dissected, occasionally compound. Inflorescence: umbel or head, simple or compound, generally peduncled; bracts present in involucres or 0; bractlets generally present in "involucels". Flower: many, small, generally bisexual (or some staminate), generally radial (or outer bilateral); calyx 0 or lobes 5, small; petals 5, free, generally ovate or spoon-shaped, generally incurved at tips, generally ± ephemeral; stamens 5; pistil 1, ovary inferior, 2-chambered, generally with a ± conic, persistent projection or platform at tip subtending 2 free styles. Fruit: 2 dry, 1-seeded halves (= mericarps), separating from each other but generally ± persistent to central axis; ribs on halves 5, 2 marginal, 3 to back; oil tubes 1–several per interval between ribs.
300 genera, 3000 species: ± worldwide, especially temperate; many cultivated for food or spice (e.g., Carum, caraway; Daucus; Petroselinum); Bupleurum lancifolium Hornem. is historical garden weed; some toxic (e.g., Conium). Mature fruit generally critical in identification, shape given in outline. Hydrocotyle moved to Araliaceae. Petroselinum crispum (Mill.) A.W. Hill is a waif. —Scientific Editors: Douglas H. Goldman, Bruce G. Baldwin.

Key to Apiaceae

Perennial herb from clustered, fibrous-tuberous roots or rhizomes, glabrous. Stem: generally decumbent or ascending, proximal nodes generally rooting. Leaf: blade oblong to triangular-ovate, generally 1–3-pinnate, leaflets wide or narrow, generally serrate to pinnately lobed. Inflorescence: umbels compound; bracts generally 0 or inconspicuous; bractlets many; rays, pedicels many, spreading or spreading-ascending. Flower: outer bisexual or staminate, occasionally bilateral; outer calyx lobes acute, generally prominent, persistent and enlarging in fruit or not; petals wide, white, tips narrowed; styles persistent. Fruit: oblong-ovate to round, ± cylindric [± compressed front-to-back]; ribs low, obtuse, corky; oil tubes generally 1 per rib-interval. Seed: face flat.
± 30 species: North America, Eurasia, Africa. (Greek: wine flower) Oenanthe pimpinelloides record based on misidentified specimen.
