Geography: Amphi-Beringian: RFE ALA.
Notes: Yurtsev: Variety vulcanorum is a prostrate-pulvinate dwarf shrub with imbricate, rotundate small leaves, persistent in winter, and globose berries.
Alsos and Elven: Subspecies vulcanorum belongs to the 'amphi-Pacific clade' of Alsos et al. (2002). It could possibly be merged with subsp. occidentale and subsp. pedris within one major genetic entity but is distinct in morphology and probably in ploidy level. These three are partly to largely overlapping in range. Subspecies vulcanorum and subsp. pedris have been observed growing together without transitions in several localities on the Chukchi and Seward peninsulas. We prefer to consider subsp. vulcanorum a low-ploid subspecies and have recombined it as such.
