Riihus Baileyaniis X frondosus. First segregated by Mr. 

 BickHell. 



Massachusetts: Quaise, Marcy's Pond, below the " Cliff," and 

 Squam, Nantucket Island, 1910, Bicknell 85, 86, 88, 87, 84. 



New Jersey: Budd's Lake, 1905, Eggleston o; Mt. Arlington, 

 1905, Mackenzie 1402; Stanhope, 2085; Berkeley Heights, 2047. 



Riihus Baileyaniis X hispidus. This was at first included in 

 R. hispidus X procumbens by Bicknell. He, however, determined 

 his Long Island material as R. Baileyaniis X hispidus.

 nell 75; Reading, 1897, Kingman. 



Rubus Baileyanus X carpinifolius. Another plant collected 

 by Eggert at Bluff Lake, Missouri, in 1878 must be, on account 

 of the combination of characters, a hybrid between R. Baileyanus 

 and R. carpinifolius, which both grow in the region. 



Rubus arenicola X hispidus. The original specimens are the 

 only ones seen of this hybrid. 



Rubus nigrobaccus X plicatifolius . The specimen referred 

 to this hybrid {Blanchard 516, sheet i), was labeled by Mr. Blan- 

 chard R. recurvans var. subrecurvans , which variety I regard as a 

 hybrid between R. recurvans and R. canadensis; but this number 

 V evidently does not belong there. The glandular pubescence of the 

 inflorescence and the cut of the leaves in the specimens mentioned 

 indicating R. nigrobaccus blood. The pubescence and the plica- 

 tion of the leaves suggest R. plicatifolius. 



Rubus nigricans X plicatifolius. I regard R. multiformis 

 Blanchard as a hybrid of R. nigricans and R. plicatifolius.
