Discussion

Variety latifolia occurs throughout the Cascade Range to Mt. Adams, Washington, where it intergrades with var. flavida, and extends to eastern Washington and northern Idaho, overlapping somewhat with the distribution of var. bracteosa.

Pedicularis rainierensis sometimes grows adjacent to this variety, and Mt. Rainier Park personnel (unpubl.) have noted putative interspecific hybrids between the two species.
