Discussion
At its morphologic extreme, var. reflexa is distinctive in its small, elliptic-oblanceolate, reflexed yellow petals, and widely branched inflorescences; however, in northern California and southern Oregon, var. reflexa and var. glandulosa completely intergrade. As circumscribed here, var. reflexa occurs at low to middle elevations in the mountains from northern Baja California, Mexico, and the Peninsular and Transverse ranges of southern California, through the Sierra Nevada to the mountains of northern California, barely entering adjacent Nevada and Oregon. Some disjunct collections from central Idaho approach this variety; their optimal disposition remains unclear.
