"Psathyrotes" is a genus of annual and perennial forbs and low subshrubs native to dry areas of southwestern North America. Common names include turtleback, brittlestem, and fanleaf.

The plants are low, densely-branching, hairy, and scaly, with a turpentine-like odor. Leaves are alternate and hairy. The Latin name of the genus (from the Greek "psathurotes") refers to the brittleness of the stems.
