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, ± glaucous; root tuberous. Stem: 0 or short. Leaf: basal, generally recurved or spreading; lowest bladeless, scarious sheaths; blades ovate to triangular-ovate, 1–3-ternately dissected, segments generally linear to lanceolate, elongate. Inflorescence: umbels compound, peduncled; bracts 0; bractlets 0–few, minute; rays few, spreading; pedicels few, 0 to short. Flower: calyx 0; petals obovate, white, tips narrowed; ovary tip projection 0. Fruit: ± ovate, compressed front-to-back; marginal ribs corky-winged, incurved, not wing-like, others thread-like; oil tubes per rib-interval several; fruit axis a corky ridge along middle of each fruit half. Seed: face ± concave.
2 species: western North America. (Greek: mountain race)
Plant 5–15 cm; tuber 3–10 mm wide, carrot-like. Leaf: bladeless sheath 2–7 cm, oblong; petiole 3–5 cm; blade 2–8 cm wide, segments 5–60 mm, linear to lance-linear, acute or obtuse. Inflorescence: peduncles 1–3, 2–15 cm, recurving; fertile rays 1–8, 5–60 mm; fertile pedicels 2–15, < 1 mm. Fruit: 3–4 mm, ovate; ribs on back obscure.
Gravelly flats, flower near melting snow; 1000–2500 m. Klamath Ranges, High Cascade Range, n High Sierra Nevada; to central Oregon. May–Jul [Online Interchange]
