Vaccinium vitis-idaea A. A. Reznicek

A circumpolar arctic-subarctic species, ranging from the tundra south in North America to New England and the Lake Superior region. Known in Michigan only from the Isle Royale Archipelago, for over a century the only known material was collected in 1868 on Smithwick Island. Finally, in 1994, E. J. Judziewicz rediscovered the species on Passage Island.

The low mats of this species perhaps resemble a diminutive individual of Arctostaphylos. The fruit is tart but tasty and where common is made into preserves or an excellent juice, much like that of the true cranberries. North American plants have been referred to var. minus Lodd., which also occurs in Eurasia.
