American Dwarf Birch (Betula glandulosa), also known as Resin Birch or Shrub Birch, is a species of birch native to North America, occurring in arctic and cool temperate areas from Alaska east to Newfoundland and southern Greenland, and south at high altitudes to northern California and Colorado in the west, and locally south to northern New York in the east. In the arctic it occurs down to sea level, while in the south of the range, it grows as high as 3400 m altitude. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...

American Dwarf Birch is a multi-stemmed shrub typically growing to 1-3 m tall, often forming dense thickets. The trunks are slender, rarely over 5-10 cm diameter, with smooth, dark brown bark. The leaves are nearly circular to oval, 0.5-3 cm long and 1.2.5 cm broad, with a toothed margin. The fruiting catkins are erect, 1-2.5 cm long and 5-12 mm broad.

It is closely related to the Dwarf Birch (Betula nana), and is sometimes treated as a subspecies of it, as B. nana subsp. glandulosa. It is distinguished from typical B. nana by the presence of glandular warts on the shoots and longer leaf petioles. Hybrids with several other birches occur.
