Cowania mexicana D.Don[1]

Purshia mexicana is a species of perennial flowering small tree in the rose family known by the common name Mexican cliffrose. It is native to western-northern Mexico, the region of the Sierra Madre Occidental cordillera.

Purshia stansburyana, native to the southwestern United States, has sometimes been included within P. mexicana.[2]

In its mostly mountainous, or higher elevation habitat, it grows in woodlands, desert, and plateau habitat.

Stenophyllanin A, a tannin, can be found in P. mexicana.[3]


The range of Mexican Cliffrose is from the western Mexican Plateau in the south, and the southern Sierra Madre Occidental cordillera north to a small region of northwest Sonora;[4] it has a continuous range in the cordillera from Chihuahua south through Durango and Zacatecas, all mostly north of the Trans-Mexican Volcanic Belt, though a few scattered locales do occur in the belt.[5]
