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 taproot or generally deep-seated tuber, glabrous to tomentose. Stem: 0 or erect, simple or branched; base fibrous or not. Leaf: blade oblong to triangular-ovate or obovate, ternately, pinnately, or ternate-pinnately dissected or compound, segments or leaflets thread-like to wide; old basal leaf sheaths fibrous-persistent or not. Inflorescence: umbels compound, peduncled; bracts generally 0; bractlets generally present, 0 to conspicuous; rays, pedicels spreading to erect, generally webbed at base. Flower: calyx lobes generally 0; petals wide, yellow, white, or purple, tips narrowed; ovary tip projection 0. Fruit: linear to obovate, compressed front-to-back; marginal ribs widely to narrowly thin or thick-winged, others thread-like; oil tubes 1–several per rib-interval; fruit axis divided to base. Seed: face flat to concave.Key to Lomatium
± 75 species: central and southern North America. (Greek: bordered, from prominent marginal fruit wing) [Constance & Ertter 1996 Madroño 43:515–521] Fruit wing width given as width of 1 wing, not both together. Lomatium roseanum Cronquist is reported from High Cascade Range, northern High Sierra Nevada, Modoc Plateau.
