delicious blueberry 

 (Vaccinium deliciosum). 



14 In the Blue Mts. area of northeastern Oregon and southeastern Washington, 

 big whortleberry shrubs tend to be less coarse and not so tall as those of the 

 Cascades; also, their leaves are paler on the under surface, relatively broader, 

 shorter, more rounded at tip, and they have smaller marginal teeth. Their 

 flowers tend toward globe-shaped, their berries are more flat-topped, average 

 smaller in size and are less juicy. These big whortleberries of the Blue Mt. area 

 are referred to the Vaccinium globulare complex by some botanists. See W. H. 

 Camp, .1 Surrey of the American Species of Vaccinium, Subgenus Euvaccinium.
