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

Annual, perennial herb, taprooted, stellate-hairy. Stem: decumbent to erect, branched. Leaf: opposite to alternate; stipules occasionally ± fused distal to node when leaves opposite; blade ovate to round, palmately lobed to compound (± entire). Inflorescence: umbels simple, few-flowered, peduncled or sessile; bracts generally present; pedicels 0 to short. Flower: calyx lobes generally 0; petals generally wide, obtuse to ± acute, tip not narrowed, not incurved. Fruit: ovate to ovoid-oblong, round, or spheric, cylindric to ± 4-angled or ± compressed front-to-back, stellate-hairy to prickly or ± glabrous; ribs obscure; fruit central axis not obvious. Seed: face ± flat.
16 species: temperate South America, 1 in California. (Wm. Bowles, Irish writer on Spanish natural history, 1705–1780) [Mathias & Constance 1965 Univ Calif Publ Bot 38:1–73]
