Of conservation concern.
The type of Townsendia microcephala may prove to be conspecific with that of T. spathulata.

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.
