Notes: FNA3: "Betula glandulosa is the characteristic dwarf birch of upland habitats throughout much of the mountainous west, occurring as well in dry open areas across the north. Where their ranges meet, B . glandulosa intergrades with both B . pumila Linnaeus and B . nana Linnaeus subsp. exilis (Sukaczev) Hultén, creating a confusing complex of intermediate forms."
KZ taxon for this species is Betula nana, Arctic Dwarf Birch and included synonyms B. glandulosa var. siberica, B. michauxii, B. nana ssp. exilis, B. nana var. siberica, B. exilis, and B. glandulosa var. hallii - all of these names have probably been misapplied.
