Discussion
Penstemon watsonii is known from mountain ranges throughout the Intermountain Region. Penstemon laxus, which has been included as a variety of this species, has corollas 2–3 mm in diameter and densely white-villous internally abaxially, and is known from south-central Idaho north of the Snake River. Penstemon watsonii does enter extreme south-central Idaho but is not known to occur north of the Snake River.
