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). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Subspecies 2 (2 in the flora). Pedicularis langsdorffii may be mistaken for P. hirsuta, P. lanata, and P. sudetica, which have similar growth forms and habitat requirements. Pedicularis langsdorffii generally has larger, pink to lavender corollas with toothed galeas that strongly arch over the abaxial lips in contrast to the smaller, toothless, pink corollas and slightly arching galeas of P. lanata. Pedicularis sudetica has up to five cauline leaves or lacks them. The straight, smaller galeas and pale pink or white corollas of P. hirsuta differentiate it from P. langsdorffii.
