Notes: Argus and Elven: Subspecies acutifolia extends from the interior of Alaska and the Yukon Territory south and east to the central Northwest Territories. There it overlaps subsp. callicarpaea and subsp. villosa (a boreal and Cordilleran race not further considered here). The leaves of subsp. acutifolia have a characteristic villous-woolly (to silky) pubescence but they may become glabrate in age. It is distinguished from subsp. callicarpaea by its larger leaves with entire margins and more acute tips, more prominent stipules, longer petioles, and catkins on shorter flowering branchlets.
