Notes: FNA3: "Betula pumila is sometimes treated (in part) as a variety of B . glandulosa Michaux, to which it is related at a subgeneric or sectional level. On the basis of morphology, however, it forms a cohesive and distinct entity (J. J. Furlow 1984). The two main varieties into which B . pumila is often divided (a more southern B . pumila var. pumila , with mostly pubescent, glandless leaves, and a more northern B . pumila var. glandulifera , with less pubescent, gland-bearing leaves) may represent geographic races; these are not well marked, however, and they do not hold up well when the complex is examined as a whole."
