﻿Rydberg: Notes ox Rosaceae 473 



Connecticut: Southington, 1906, Blanchard loi, set 3 14. 



Missouri: Little Blue Tank, 1897, Mackenzie 210.

Ruhus Baileyanus X frondosiis. First segregated by Mr. 

 Bicknell.

 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. 



Rubus Baileyanus X hispidus. This was at first included in 

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

 his Long Island material as R. Baileyanus X hispidus.

Rubus Baileyanus X carpinif alius . 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. carpinif alius , which both grow in the region. 



Rubus arenicola X hispidus. The original specimens are the 

 only ones seen of this hybrid. 



Rubus nigrobaccus X plicatij alius. 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 

 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. plicatif alius. 



Rubus nigricans X plicatif alius. I regard R. midtijormis 

 Blanchard as a hybrid of R. nigricans and R. plicatif alius.
