APIACEAE (Umbelliferae) CARROT FAMILY

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.

APIUM
Biennial, perennial herb, taprooted or fibrous-rooted from rhizome. Stem: prostrate to erect, hollow, generally rooting from proximal nodes, glabrous. Leaf: blade oblong to obovate, 1-pinnate, leaflets paired, lanceolate to ± round. Inflorescence: umbels compound, peduncled or not; bracts, bractlets conspicuous to 0; rays, pedicels few, spreading-ascending. Flower: calyx lobes 0 or minute; petals wide, white to ± green-white; ovary tip projection occasionally flat. Fruit: ovate-oblong to round, compressed side-to-side; ribs ± equal, thread-like to obtuse and ± corky; oil tube 1 per rib-interval; fruit axis entire or notched at tip. Seed: face flat.
2n=22.
± 20 species: generally southern hemisphere, also Eurasia. (Classical name for celery)
