The above synonymy has reference only to the Sierran representa- 

 tion of this variable species ; definitive treatment of the many phases 

 exhibited by the plant in different situations must be the work of some 

 future monographer, though already it is evident that the above 

 list of synonyms might be greatly extended.

The typical form of the species has discoid heads but occasionally 

 plants show heads with more or less asynmietrical peripheral corollas, 

 i.e., radiate heads are produced and constitute the var. fallax Greenm.

 Idaho and western Nevada.

I am uncertain whether this species should be admitted to this list, 

 since it is infrequent above the Transition. Following the description 

 appears the note : ' ' Common in grassy wet meadows along the eastern 

 base of the Sierra Nevada, Calif."
