Williams combleaf
Polyctenium williamsiae
Polyctenium is a genus of flowering plants in the family Brassicaceae. It contains a single species, Polyctenium fremontii, the desert combleaf, a small and compact plant native to the northern Great Basin region of the Western United States. The plants are known by the common name combleaf, owing to the resemblance of their deeply lobed leaves to a comb. It grows in sagebrush shrub steppe in northeastern California, southeastern Oregon, southwestern Idaho, and northwestern Nevada.
