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.
