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: Annual, biennial, taprooted, hairy. Stem: decumbent or erect, generally +- branched. Leaf: blade oblong, pinnately dissected, segments linear to lanceolate. Inflorescence: umbels compound; bracts, bractlets generally present; bracts conspicuous, generally pinnately lobed; bractlets entire to toothed; rays generally many, spreading, in fruit incurved to form nest-like umbel. Flower: outer occasionally +- bilateral; calyx lobes 0 or evident; petals wide, white, margins occasionally +- red, tips narrowed, unequally 2-lobed. Fruit: oblong to ovate, compressed front-to-back; ribs 10, 1° thread-like, bristly, 2° winged, prickly; oil tubes 1 beneath each 2° rib; fruit axis entire or notched at tip.

2. County and Jepson Region polygons can be turned off and on using the check boxes.
(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
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.
