Common Name: CARROT FAMILY Habit: 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. Genera In Family: 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). Note: Mature fruit generally critical in identification, shape given in outline. Hydrocotyle moved to Araliaceae, Orogenia moved to Lomatium, Sphenosciadium moved to Angelica. Petroselinum crispum (Mill.) A.W. Hill is a waif. eFlora Treatment Author: Lincoln Constance & Margriet Wetherwax, except as noted Scientific Editor: Douglas H. Goldman, Bruce G. Baldwin.
Habit: 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, wings generally not incurved; oil tubes 1--several per rib-interval; fruit axis divided to base or a corky ridge along the middle of each fruit half. Seed: face flat to concave. Etymology: (Greek: bordered, from prominent marginal fruit wing) Note: Fruit wing width given as width of 1 wing, not both together. eFlora Treatment Author: Lincoln Constance & Margriet Wetherwax Reference: Feist et al. 2017 Phytotaxa 316:95--98.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
