Treatment appears in FNA Volume 19. Treatment on page 319. Mentioned on page 318.

Plants rhizomatous or with woody caudices. Herbage glabrous or ± arachnose. Stems 1 (plants rhizomatous) or 2–3+ (plants with woody caudices), erect, freely branched, herbaceous, relatively leafy distally. Cauline leaves: proximal not pinnately lobed (lanceolate to lance-linear, margins entire or denticulate, apices acute to acuminate); distal lanceolate or elliptic to linear, margins entire or denticulate, apices acute to acuminate. Arrays of heads relatively crowded. Cypselae 2–2.5 mm. 2n = 18.


Phenology: Flowering Mar–Dec.
Habitat: Crumbling shale along roadcuts, in canyons, chaparral, foothill woodlands
Elevation: 200–1600 m
