Notes: Elven and Murray: The types behind the names subsp. longifolia and subsp. czukczorum should be compared. As the names were published one year apart, we assume that they belong to the same taxon and that the authors were unaware of the each others' publications. This race is the predominant one in Lavrentiy Bay from where subsp. longifolia was described.
Subspecies longifolia is common on the American side in western Alaska north and east to the western Brooks Range (on the northern coast as rare east to Demarcation Point) and to the Kobuk and Yukon river valleys. It is the exclusive race in southwestern and south-central Alaska, e.g., in the Goodnews Bay area, Alaska Peninsula, and in Kodiak and smaller offlying islands.
