This member of the Asteraceae family was given this name in 1891 by Edward Lee Greene. It is found in the U.S.A. and Northern Mexico, growing in a well drained soil with some water and lots of sun. The caudex will grow to three centimetres, and the plant to 50 centimetres. The flowers are yellow, and the plant can only be reproduced by seeds.

The genera name from the Greek psilo; 'naked' and trophe; 'loving' or 'to turn'. The species name after Dr. James G. Cooper, 19th century geologist.
