Comments: This plant is listed as an endangered species by the U.S. Fish and Wildlife Service. The small patch of it in the Verde Valley is threatened by development and road building in the area, where it is in the path of a proposed link between major thouroughfares. This plant can be distinguished from Cliffrose (Cowania mexicana), which is far more common and widespread, by it's small size and by the fact that the leaves are generally linear, although some specimens show two subapical teeth. C. mexicana leaves are pinnately lobed.
Purshia subintegra also seems to be limited to the limestone outcroppings and shelves in the Verde Formation in our area. See also the Cliffrose page.
