Eriogonum batemanii is fairly common throughout its range in northwestern Colorado (Moffat and Rio Blanco counties) and east-central Utah (Carbon, Duchesne, Emery, Garfield, Grand, and Uintah counties). In Duchesne County it hybridizes with E. shockleyi, producing an unnamed but distinctive hybrid. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
