Discussion

Varieties 3 (3 in the flora).

The coiled beak that extends directly downward from the top of the galea is distinctive in Pedicularis contorta. Seen from the side, the large, upward-expanded, lateral lobes of the abaxial lip surround the beak, concealing it from view. The flowers of P. contorta are very similar to those of P. racemosa; however, the leaves of P. racemosa are undivided, the beak curves down and to one side, and the inflorescence often branches, forming a panicle of short racemes with long internodes between flowers.

Flower and calyx color and width of the subtending floral bracts delimit three varieties in Pedicularis contorta; corolla color is difficult to discern in herbarium specimens. The following key is adapted from R. N. Reese (1984).

Reese noted that the center of distribution of var. rubicunda was Clearwater County, Idaho, and adjacent Ravalli County, Montana. Intermediates are common between var. contorta and var. rubicunda in areas of sympatry where the same species of Bombus pollinate both varieties during foraging (Reese).
