Discussion
Variety oblongifolium is the widespread and rather common tetraploid phase of the species, being the only expression with pubescent flowering stems. It occurs from southern Oregon south to northern California and western Nevada. The plants vary in flower color. This variety and var. pubiflorum occasionally grow together. In such instances, differentiation between the two based on the presence or absence of tomentum can be arbitrary.
