Eriogonum batemanii M. E. Jones

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.
