BRAINERD & PEITERSEN'S BLACKBERRIES OF NEW 
ENGLAND. 
M. L. FERNALD. 
Dvurtnc more than a decade Mr. W. H. Blanchard stirred Ameri- 
can botanists as they had not before been aroused to the importance 
of closely studying the native blackberries, and set an example of 
marvelous devotion and self-sacrifice: in his declining years aban- 
doning his remunerative pursuits and spending his meagre savings 
and complete energies in an attempt to throw light upon the hitherto 
hardly appreciated complexities of the American blackberries. In 
Blanchard's own words, “This search has continued and is now ten 
years old. I have searched throughout the whole of the eastern 
part of the United States and Canada as far west as blackberries 
are found, or from St. John's, Newfoundland, to Lake Winnipeg in 
Manitoba, and south to Florida . . . . . making the search 
as complete as my time and limited means would allow." As a 
result of his unprecedented activity twenty-two papers on the black- 
berries were published before impaired eyesight and age forced him to 
relinquish his keen and untiring studies of an amazingly difficult 
problem. Fortunately, however, before giving up active work he 
was able to summarize his conclusions in a very valuable paper? in 
which he recognized in northeastern America the following 16 as true 
species: Rubus canadensis L., R. allegheniensis Porter, R. Andrews- 
ianus Blanchard, R. hispidus L., R. procumbens Muhl., R. trivialis 
Michx., R. recurvans Blanchard, R. cuneifolius Pursh, R. frondosus 
Bigelow, R. setosus Bigelow, R. semisetosus Blanchard, R. vermont-
