436 BLANCHARD: RUBUS OF EASTERN NORTH AMERICA 
in 1891 Prof. C. H. Peck found at the base of the Adiron- 
dacks a peculiar setose, erect or partly erect blackberry, he gave 
it a new name, R. hispidus var. suberectus. In 1901, in Britton’s 
New Manual, Rydberg raised this to specific rank since it 
differed a good deal from Bigelow’s two specimens of R. setosus. 
He could not use Peck’s varietal name as it would be a homonym, 
so he published it as R. nigricans, Peck’s dewberry. This was the 
first segregation. This plant is the erect or nearly erect, often 
erect, 5-foliolate, soft-stemmed, densely soft-bristled form, having 
abundant glandular hairs, the common form in moist situations 
at low altitudes, and often in dry places at higher altitudes—the 
common form in Vermont and New Hampshire. In Connecticut 
it is found in low places. The type specimen is figured‘in Bailey’s 
Evolution of Our Native Fruits and in the Illustrated Flora. 
Another segregate is R. semisetosus, published by me in Rhodora 
9: 8. 1907. This prefers dry land, has terete, hard stems, is 
seldom quite erect, and has retrorse, bristle-pointed prickles; it is 
especially abundant in Connecticut on the sand plains. Still 
another segregate appears in Rhodora 8: 213. 1906 as R. hispidus 
var. major. Some forms of R. hispidus are so coarse, so different 
from the most hispid forms that appeal to one as R. hispidus, that 
a name and a place for them seems desirable. 
There is yet another plant having a slight suggestion of 
this group and very abundant in Vermont, especially in the 
higher parts, which I named and described in the American 
Botanist for July 1904, p. 1, as Rubus vermontanus. This was 
mistakenly assumed by the authors of Gray’s New Manual to be 
R. nigricans Rydb. There is still left a large amount of this 
setosus aggregate to which to apply the name R. setosus after these 
segregations have been made, especially of the decumbent, soft- 
- bristly, trifoliolate forms. 
In Maine and the maritime provinces of Canada there are 
four species that have a wide range, all of which were described 
by me in Rhodora in 1906. | Rubus amabilis, since renamed Rubus 
amicahs, ranges from southwestern Maine to the Gulf of St. 
Lawrence. While I have not yet found any new stations in 
Maine, I have collected it in many places in southern New Bruns- 
wick and in Nova Scotia, where it is especially abundant in the
