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, glabrous, generally glaucous; roots tuberous, single or clustered, or clustered-fibrous. Stem: erect, branched. Leaf: blade lanceolate to triangular-ovate, generally 1–2-ternate-pinnate or 1–2-pinnately or ternate-pinnately dissected, leaflets or segments generally linear to lance-linear. Inflorescence: umbels compound; bracts 0–many, conspicuous and reflexed or not; bractlets several to many, narrow, ± scarious; rays, pedicels few to many, generally spreading-ascending; 2° umbels generally convex distally. Flower: calyx lobes evident; petals generally obovate, white, tips narrowed. Fruit: linear-oblong, ± compressed side-to-side or not at all, glabrous; ribs ± equal, thread-like to prominent, not winged; oil tubes 1–several per rib-interval; fruit axis divided to base. Seed: face flat to grooved.Key to Perideridia
