  I'm trying to figure out the various highbush blueberries (and maleberries?) Is this beautiful leaf enough to go on? Taken at Nickerson State Park in Brewster, MA 8/30/20. Thanks!

  Answer

  Dear corylus, good afternoon. Two ways to identify these genera apart involve examining the branchlet surfaces and winter buds. Those of Vaccinium (blueberry) have +/- white bumps (papillae) on the branchlet surfaces and have multiple, imbricate scales covering the winter buds. Those of Lyonia (maleberry) have no papillae on the branchlet surfaces and have two valvate buds scales covering the winter buds.
