Discussion

The distribution of Vaccinium vitis-idaea in North America extends from northwestern Greenland at 77° north latitude, south to Connecticut at 42° north latitude, and from 45° west longitude (southern tip of Greenland) west to 170° west longitude (Aleutian Islands); it is rare in Connecticut (not collected since the late 1800s), Massachusetts, Vermont, and Wisconsin. This species has been erroneously reported from New York; it hybridizes with V. myrtillus in northern Europe, producing V. ×intermedium Ruthe. The hybrid might be anticipated in North America, but the two species are not known to occur together anywhere in the flora area.
