Discussion

Variety glutinosum is the common yellow-flowered expression of the species. It occurs in Arizona (Coconino, Mohave, Navajo, and Yavapai counties) and Utah (Beaver, Emery, Garfield, Iron, Kane, Washington, and Wayne counties). Yellow-flowered plants in Garfield and Wayne counties of Utah might be better assigned to var. corymbosum.
