Oreonana vestita
WOOLLY MOUNTAIN-PARSLEY


Higher Taxonomy
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, Orogenia moved to Lomatium, Sphenosciadium moved to Angelica. 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. Leaf: basal-most bladeless sheaths; distal blades narrowly ovate to round, pinnately or ternately dissected, segments lanceolate or oblong. 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.
Species In Genus: 3 species: high mountains of CA-FP. Etymology: (Greek: mountain dwarf)

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.
