Heterotheca zionensis

A common plant of roadsides and drier areas in the mountains. Traditionally, this has been considered to be an endemic of northeastern Arizona and southeastern Utah with occasional introduced populations elsewhere, however the circumscription of H. zionensis is apparently in some amount of flux and recent annotations by G.L. Nesom of plants at NMC suggest a broader circumscription, including plants formerly included in H. villosa.
