  • FNA page for Betula nana "The range of Betula nana subsp. exilis stretches through Siberia and across northwestern North America. It is sometimes confused with Betula glandulosa Michaux; it can be distinguished from that species by its usually much smaller, rounded to truncate-tipped leaves that have teeth all the way to the base (the base being mostly toothless in B . glandulosa ). Betula nana subsp. exilis has been combined into B . glandulosa by several authors (E. H. Moss and J. G. Packer 1983; A. E. Porsild and W. J. Cody 1980). The two taxa hybridize and form a sometimes bewildering assortment of intermediates in the extensive region where their ranges overlap; they constitute well-defined entities away from the area of contact.
