Discussion | The flowers of Vaccinium pallidum are visited primarily by Andrena carlini Cockerell and Bombus spp. This species occasionally hybridizes with V. angustifolium, yielding V. ×dobbinii Burnham. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Vaccinium macrocarpon is introduced and escaping elsewhere (British Columbia, Oregon, Washington) with respect to its normal range in eastern North America. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
