Discussion

Variety laricifolius is known from south-central Montana and central and western Wyoming. The type material (Snake County, Tolmie s.n., K) reputedly came from southern Idaho. D. D. Keck (1937) expressed doubt; no other collections are known from Idaho, so the variety is excluded from that state.
