Revision as of 20:28, 16 December 2019
Leaf faces glabrous or hirtellous. Heads in loose, corymbiform arrays. Involucres hemispheric to globose, 7–10 mm wide. Rays 0.
Distribution
sw United States.
Discussion
Varieties 2 (2 in the flora).
The two varieties were mapped as geographically intermingling in southern California (M. A. Lane 1988). Considerable variation in expression of vestiture occurs in the area where the hirtellous-leaved plants grow and identifications should be recognized as arbitrary.
Selected References
None.
