400 BicknetL: Have WE ENoUGH New ENGLAND BLACKBERRIES ? 
what the supposed species is or should be expected to be, and 
weak forms of a number of different blackberries have been re- 
ferred to it. Among specimens so determined, spindling forms of 
R. canadensis are clearly to be recognized, and I have seen a few 
specimens of aberrant plants which actually suggested a cross 
between R. canadensis and R. triflorus Rich. 
RUBUS ALLEGHENIENSIS Porter. 
R. glandicaulis Bld. 
>< CANADENSIS: See under R. canadensis. 
x ARGUTUS: Nantucket; Long Island. 
> FRONDOsUsS: Nantucket; Long Island. 
X NIGRICANS: R. frondisentis Bld. 
< Hispipus: R. permixtus Bld. R. flavinanus Bld. is perhaps 
a form of this cross or possibly a compound hybrid involv- 
ing R. nigricans, 1. e., R. allegheniensis K vermontanus. 
> PROCUMBENS: Long (aaa. 
< ENSLENI: R. invisus Bailey is possibly to be papliined as 
a hybrid of these species. Certain herbarium specimens, 
presumably authentic, readily allow the suggestion, but, 
never having seen the living plant,I may altogether mis- 
understand it. 
 BatLeyanus: Long Island. R. Jeckylanus Bld. 1 think may 
be referred here. 
Rubus sativus Brainerd, a name for which, I believe, President 
Brainerd through some misadventure of editor or printer was un- 
intendedly on his part made to stand sponsor, represents a plant 
which I am inclined to regard as a weakened shade form of R. 
allegheniensis or perhaps some mixture of that species and R. 
Baileyanus. 
RuBUsS ARGUTUS Link. 
R. floricomus Bld. 
R. Andrewsianus Bld. 
R. amnicolus Bld. 
 ALLEGHENIENSIS: Nantucket; Long Island. 
> FRONDOsUsS: Nantucket; Long Island. 
X NIGRICANS: R. ascendens Bld., in part. Nantucket; Long 
Island. 
X HIsprpus: Long Island.
