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.) |
Pedicularis chamissonis differs from P. verticillata by having leaves and flowers about 1.5 times larger with a galea that is extended into a conical beak, leaves lanceolate versus elliptic, and lateral lobes of the abaxial lip more than twice the size and more pendulous. Pedicularis chamissonis is chiefly an Asian species, found on the Kamchatka Peninsula, Kuril Islands, Sakhalin Island, and Japan; the only North American populations occur in the Aleutian Islands of Alaska.
