This widespread circumpolar species is found in North American and Eurasia. Argus et al. (2012), in Flora North America (2012), indicate that one subspecies has been identified: "A population of Salix reticulata on the Queen Charlotte Islands, with consistently glabrous ovaries, was named subsp. glabellicarpa. Some southeastern Alaska populations have plants with glabrous, partially hairy, and completely short-silky ovaries growing together. The possibility that subsp. glabellicarpa may be a hybrid or a simple mutation needs study."
