Recorded Range: Chaetopappa ericoides is found in the southwest part of North America in AZ, CA, CO, KS, NE, NM, NV, OK, TX, UT and WY and northern Mexico.

Comments: As evidenced in the recorded range above, and Flora of North America, this species is "widespread and highly variable in the type and amount of pubescence as well as other features." Perhaps this species has acquired, or is in the process of acquiring more facultative strategies which enable it to expand its geographic area beyond that of the typically more limited obligate desert species.
This plant was made into a poultice or infusion by the Acoma and Laguna Indians of New Mexico and used for swelling and by the Havasupai as a pediatric aid. See the complete species account from Native American Ethnobotany, University of Michigan, Dearborn.
