Elevation: 1400-1500 m
Discussion
Variety atwoodii is known only from two locations, one near Fredonia, and a second along the Honeymoon Trail, both in Mohave County. It appears to be an established, albeit rare, variety that probably is the result of past hybridization involving E. thompsoniae var. albiflorum and E. mortonianum. The Bureau of Land Management in Arizona considers Atwood’s wild buckwheat a taxon of special concern.
