Townsendia scapigera
Townsendia glabella
Plants that key here and have peduncles 5–15+ mm (sporting smaller heads, fewer ray florets, and smaller cypselae than are characteristic of Townsendia scapigera) may belong to T. jonesii (which see). Plants included here in T. scapigera from Sweetwater Mountains, California, with relatively large heads and high numbers of florets were identified on their labels (e.g., DeDecker 3928, RSA) as T. parryi, a species not known to occur in California.

Of conservation concern.
Distinctions between Townsendia glabella and T. rothrockii are subtle. Types of the two names are probably better considered to be conspecific.
