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.

ERYNGIUM

Robert E. Preston, Michael S. Park & Lincoln Constance

Biennial, perennial herb; taprooted, roots clustered, or rhizomes; generally glabrous, ± spiny. Stem: decumbent to erect, generally branched. Leaf: basal rosette, cauline; petioles present or 0; blades linear to triangular-ovate or round, generally pinnately or palmately lobed or dissected (entire), generally sharp-toothed or spine-tipped, net-veined; juvenile leaves linear, segmented. Inflorescence: heads 1–many in cymes, racemes [panicles]; bracts each generally subtend 1 flower, with scarious membrane enclosing ovary, outer > to >> inner, spiny or not on margins and abaxially; rays, pedicels 0. Flower: sepals spine-tipped, generally persistent; petals oblong to ovate or oblanceolate, white to blue or purple, tip long; anthers, styles generally green, occasionally blue; ovary tip projection 0. Fruit: obconic to obovate or narrowly elliptic [round], compressed or not, densely scaly; scales at fruit tip and along juncture of carpels generally larger, longer than on face or base; ribs 0; oil tubes obscure; fruit central axis not obvious. Seed: face generally flat.
± 230 species: America, Eurasia, Australia, New Zealand. (Ancient Greek name used by Theophrastus) [Marsden & Simpson 1999 Madroño 46:61–64] California species variable, intergrading, need study.

Key to Eryngium

E. vaseyi J.M. Coult. & Rose COYOTE-THISTLE
NATIVE
Glabrous. Stem: decumbent to ascending or erect, 1.5–5 dm, main stem branched 0–5 cm distal to rosette. Leaf: petiole 1–4 cm; blade 8–24 cm, >> petiole, lanceolate to oblong, deeply pinnately and sharply lobed. Inflorescence: heads 8–13 mm, ± spheric, in cymes; peduncle generally 1–4 cm; bracts 8–25 mm, linear, margins spiny. Flower: sepals 2–3 mm, ovate, generally entire, abruptly narrowed to tip-spine; petals oblanceolate to oblong, white; styles 2–2.5 mm, >= sepals. Fruit: 2–2.5 mm, obovate; scales dense, ± equal to unequal, ovate or awl-like, acute.
2n=32. Occasionally misapplied to Eryngium aristulatum and Eryngium castrense, now with persistent nomenclatural confusion. [Online Interchange]
