Discussion

Pedicularis crenulata is abundant in moist swales of alpine to subalpine sagebrush meadows of the mid to southern Rocky Mountains, as well as California and Nevada, where large populations with their reddish violet flowers create a distinctive swath across the otherwise green landscape. The undivided, nearly linear leaves with two-crenate margins are unique among North American species of Pedicularis. The galea bears a single apical tooth on each abaxial margin at the distal tip. Other species with the combination of two calyx lobes and undivided, linear to nearly linear leaves are P. angustifolia and P. racemosa.
