Rydberg cites with some doubt the Macoun nos. 21,183 and 
21,193 from Sable Island as Rubus nigricans X recurvans, Bull. Torr, 
Bot. CI. xlii. 476 (1915); and on the following page he cites no. 
21,193 as Rubus nigricans X procunibms. On p. 478 he cites the C. 
B. Robinson no. 574 as Rubus hispidus X nigricans. 
An anonymous writer reports "blackberries" on Sable Island 
(All the Year Round, Ix. 521, 1890). 
This species of the Maritime Provinces and Cape Cod dill'ers from 
R. tardatus Blanchard by having broadly obovate more coriaceous 
leaflets, abundant strong prickles, densely villous and ordinarily 
glandless but bristly pedicels; instead of the broadly lanceolate 
leaflets tapering to each end, the less numerous weaker prickles, 
and the less pubescent and copiously glandular pedicels of that 
species; from R. sctosus Bigel. by having strong ])rickles thickened 
at the base and broad ol)()vate l)luntly serrate dark green coriaceous 
leaflets, instead of flne setae and narrower oblanceolate sharply 
serrate paler leaflets, long-trailing tips of the branches and essen- 
tially glandless pedicels; from R. hispidus L. by its much coarser 
habit, strong prickles, larger leaves, and its more elongate coarser 
inflorescence with larger corolla and larger seeds (averaging 3 nun. 
in length), the comparatively delicate /\'. hispidus ha\ing fine weak 
prickles and more rounded smaller leaflets and small fruits with seeils 
averaging 2 nun. in length.
