A PUBESCENT VARIETY OF VACCINIUM VACILLANS. 
M. L. FERNALD. 
Mr. GEoRGE L. Kirk has recently sent from Rutland, Vermont, 
specimens of a Vaccinium which has all the characteristics of the 
common V. vacillans Kalm except that its mature leaves and twigs 
are pubescent. In the words of Mr. Kirk: “The blueberry I find 
on a dry sandy hillside, growing near ledges with typical Vaccinium 
vacillans and differing from it in the slight pubescence of the under 
side of the leaves. It occurs only in small quantities while the ordi- 
nary species of blueberries grow in abundance in favorable localities 
on different parts of the same hill." Typical V. vacillans has the 
twigs and foliage quite glabrous and the pubescent extreme of the 
species has more than once caused some questioning among those 
who know it. In 1870 the same variation was collected at Rolla, 
Missouri, and upon the specimen sent to Dr. Gray, the collector com- 
mented: “Most like V. vacillans but leaves... .pubescent beneath.” 
Others have collected the plant, and we now know it from a wide 
range of territory. As a variety it seems well marked and is parallel 
to V. pennsylvanicum, var. myrtilloides (Michx.) Fernald discussed in 
1908 (Ruopora, x. 147). This extreme variation of V. vacillans 
may be called
