Discussion

The current circumscription of Townsendia jonesii is, perhaps, too lumpy. Some lumps might be better treated as distinct species and/or included within the circum-scription of T. scapigera.

Of conservation concern.

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