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.

Pedicularis sylvatica is considered by L. Brouillet et al. (http://data.canadensys.net/vascan/) to be introduced in the flora area. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
