Discussion

Subspecies glauca occurs along the coast of the Alaska Peninsula, Aleutian Islands, Kodiak Island, the Pribilov Islands, and, intermittently, to Teller on the Seward Peninsula. Transitional basal leaf forms occur where subsp. glauca is sympatric with subsp. lanceolata; subsp. glauca is then distinguished in most cases by having shorter stamen filaments. Some specimens are difficult to place in either subspecies in this zone of contact.
