Discussion
Variety ambusticola is known from mountains of western Riverside County to the San Francisco Bay area and northern Sierra Nevada foothills. It occurs at about the same elevations as, and intergrades extensively with, var. robustior in northern California (J. D. Morefield 1992c).
Depauperate individuals of var. ambusticola are among the smaller and more inconspicuous Compositae, sometimes consisting of just one grayish head embedded in a leaf rosette on a root 1–2 cm long.
