Vaccinium uliginosum
Vaccinium membranaceum
Vaccinium uliginosum is transcontinental in North America between 60° and 70° north latitude; farther north it is rare, especially in the Queen Elizabeth Islands. To the southwest, it is found as far as northern California and northwestern Utah. The summits of the White Mountains of New Hampshire form its southernmost limit in eastern North America. This wide-ranging plant shows considerable variation, notably in floral morphology. Subspecies have been recognized (cf. S. B. Young 1970); a review of morphological variation by H. J. Warr (1981) did not support the distinctiveness of infraspecific taxa.

Vaccinium membranaceum is, by far, the most widely commercially utilized western huckleberry for fruit and is harvested extensively from the wild. This species served as an especially important source of food for native peoples throughout western North America, and the dried berries were used for winter food and trade.
