Annual to tree
Leaves basal or cauline, alternate to whorled, simple to compound
Inflorescence: 1° inflorescence a head, each resembling a flower, 1many, generally arrayed in cymes, generally subtended by ± calyx-like involucre; flowers 1many per head
Flowers bisexual, unisexual, or sterile, ± small, of several types; calyx 0 or modified into pappus of bristles, scales, or awns, which is generally persistent in fruit; corolla radial or bilateral (rarely 0), lobes generally (0)45; stamens 45, anthers generally fused into cylinder around style, often appendaged at tips, bases, or both, filaments generally free, generally attached to corolla near throat; pistil 1, ovary inferior, 1-chambered, 1-seeded, style 1, branches 2, generally hair-tufted at tip, stigmas 2, generally on inside of style branches
Fruit: achene, cylindric to ovoid, generally deciduous with pappus attached
Genera in family: ± 1300 genera, 21,000 species (largest family of dicots): worldwide. Largest family in CA. Also see tribal key to CA genera: Strother 1997 Madroño 44(1):128. See glossary p. 25 for illustrations of general family characteristics.
Annual, biennial, perennial herb from taproot; sap milky
Stems erect, < 8 dm
Leaves basal or cauline, entire to pinnately lobed
Inflorescence: heads ligulate, clustered in cymes; phyllaries in 2 distinct series; receptacle naked
Flowers 560; ligules yellow, readily withering
Fruit tapered at both ends, sometimes beaked; pappus of many soft, hair-like bristles
Species in genus: ± 200 species: especially n hemisphere
Etymology: (Greek: sandal, for unknown reason)
Sexual forms of native species are distinct but (except C. nana, C. runcinata) connected by many asexually reproducing forms of hybrid origin that obscure boundaries. Asexual forms are all placed in the same sp. as sexual forms, except for the asexual group described under the name C. intermedia, for which no key is attempted
Horticultural information: TRY.
Perennial from taproot
Stems 1.56 dm, generally branched near base, tomentose to ± glabrous
Leaves: basal 728 mm, lanceolate, entire or with widely separated, triangular lobes; cauline leaves much reduced, generally not lobed
Inflorescence: heads 740 in cymes; involucre 8.517 mm; outer phyllaries small, lanceolate to deltate; inner phyllaries 58, small, lanceolate to deltate, thin and densely hairy near margins, thicker and nearly glabrous along midrib
Fruit 58 mm, with 10 prominent ribs, beakless, brown; pappus dusky to white
Chromosomes: 2n=22,33,44, 55,77,88
Ecology: Dry, lightly wooded or open slopes, often on serpentine
Elevation: 4001900 m.
Bioregional distribution: Klamath Ranges, Outer North Coast Ranges, High North Coast Ranges, High Cascade Range, n High Sierra Nevada
Distribution outside California: to Washington
|YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).|
