Acer glabrum Torr.
Rocky Mountain maple
Aceraceae (Maple Family)
Rocky Mountain maple is a multi-stemmed, 10-30 ft. tree or shrub with a 10-15 ft. spread. Though inconspicuous, the early spring flowers of this maple are quite fragrant. Its shiny, green, deciduous leaves turn yellow to reddish-orange in fall. Smooth, gray bark; red twigs; and reddish, winged seeds provide winter interest. The northernmost maple in the New World, it extends through southeastern Alaska. The Latin species name, meaning hairless, refers to the leaves.
