Family: Apiaceae (Umbelliferae)View DescriptionDichotomous Key

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. Petroselinum crispum (Mill.) A.W. Hill is a waif.

Genus: OreonanaView DescriptionDichotomous Key

Habit: Perennial herb, taprooted, cushion-forming, generally coarsely hairy or tomentose. Stem: 0.

Inflorescence: umbels compound, head-like, spheric or hemispheric; peduncles spreading; bracts 0; involucel 1-sided, bractlets fused to +- free; rays few to many, spreading to spreading-ascending; fertile pedicels short, sterile > fruit. Flower: bisexual, staminate, or sterile; calyx lobes conspicuous or not; petals spoon-shaped or oblanceolate, generally white or yellow, or purple in age, early-deciduous, tips narrowed; ovary tip projection 0. Fruit: ovate to round, +- compressed side-to-side to cylindric, hairy; ribs +- equal, thread-like; oil tubes several per rib-interval; fruit axis divided to base. Seed: face deeply grooved.
