Revision as of 18:42, 24 September 2019

Leaf faces glabrous or hirtellous. Heads in loose, corymbiform arrays. Involucres hemispheric to globose, 7–10 mm wide. Rays 0.

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.
