2.  Vaccinium boreale Hall & Aalders N

northern blueberry. Vaccinium pensylvanicum Lam. var. angustifolium (Ait.) Gray; 
 V. pensylvanicum Lam. var. alpinum Wood • ME, NH, VT. Found mainly at high elevation on 
alpine ridges and plateaus, also growing on low elevation balds and coastal peatlands 
in eastern ME. Reports by Seymour (1982) of Vaccinium angustifolium var. angustifolium mostly refer to this species. Vaccinium boreale most closely resembles V. angustifolium, 
and forms of the latter sometimes have small, narrow leaf blades that approximate the dimensions of V. boreale. However, Vaccinium boreale is a shorter, more compactly branched plant that flowers 10–20 earlier than V. angustifolium (regardless of leaf dimensions).
