Such a classification to be of the maximum value should have 
been made by one familiar with the various species throughout 
the whole extent of their ranges. Species that appear to the writer 
to fruit abundantly may fruit so much more abundantly in other 
regions that their fruit in the Sugar Grove area would be scarce 
by comparison. The wintergreen, Gaultheria procumbens, is a 
case in point. The berries are apparently sufficiently common to 
supply enough seed for the perpetuation of the species, and the 
plant would accordingly have been classed as fruiting freely but 
for the acquaintance of the writer with the same species in New 
England where the berries are borne in such great profusion—six 
+ Species confined to the southern portion of the area.
