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

Plants rhizomatous or with woody caudices. Herbage glabrous or sparsely hairy (arachnose). Stems usually 1, erect, branched distally, proximally woody, relatively densely leafy distally. Cauline leaves: proximal (1–) 2-pinnately lobed (lobes linear, apices obtuse or acute), ultimate margins entire or denticulate, apices usually obtuse; distal linear to filiform (sometimes pinnately lobed, lobes linear to filiform). Arrays of heads relatively crowded. Cypselae 1.8–2.2 mm. 2n = 18.


Phenology: Flowering Feb–Dec.
Habitat: Clay flats or canyon slopes
Elevation: 50–400 m
