Discussion

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.
