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]
Distribution edit
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;[2] 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.[2]
Uses edit
The plant is browsed by deer, cattle, and sheep, and is particularly important to these species during the winter.[4]
Native Americans made ropes and clothing from the bark, and fashioned arrow shafts from the stems.[4]
