TAXONOMY : 
The currently accepted scientific name of bog birch is Betula glandulosa
Michx. [4,25,63].

An abundance of intermediate forms makes a precise distinction between
bog birch (Betula glandulosa) and swamp birch (Betula pumila) difficult.
This taxonomic uncertainty results in intermediates regarded as either:

    Betula glandulosa Michx. var. glandulifera (Regel) Gleason [17,23]

or  Betula pumila L. var. glandulifera Regel [4,25].

This paper recognizes these intermediate forms as Betula pumila var.
glandulifera, as more recent authorities do [4,6,25].  However, due to
the continued uncertainty over their proper taxonomic placement,
information on these plants will be incorporated into this paper, and
they will be cited as Betula pumila var. glandulifera.

This paper does not recognize any subspecies, varieties, or forms of
Betula glandulosa.

Numerous hybrids have been described within this group including [4,6]:
