Discussion

Of conservation concern.

Chaenactis parishii is sometimes cultivated in rock gardens. It is known from small, isolated populations in the higher Peninsular Ranges of Riverside and San Diego counties and adjacent Baja California. Chaenactis parishii and C. suffrutescens form a species pair well marked by the (usually) subshrubby habit, proximal indument persistent, white, felty, heads relatively large, and largest leaf blades lance-ovate to deltate.
