﻿Rydberg: Notes on Rosaceae 477 



Ontario: Cranberry Lake, Algonquin Park, 1900, Macoun 

 24696a. 



Maine: Sangerville, 1895, Fernald 244. 



Ruhus nigricans X Randii. Only the specimens of the 

 original collection have been recorded. 



Rtibus Baileyanus X nigricans. This was first recognized 

 by Mr. Bicknell. C. C. Curtis's specimens have much narrower 

 leaflets and are doubtfully referred to it. 



New York: Hempstead Plains, 1910, Bicknell 15; between 

 Yonkers and Mount Vernon, 1903, C. C. Curtis; Van Courtlandt 

 Park, 1896, Bicknell. 



Connecticut: Plainville, 1904, Andrews 26; Southington, 

 1903, Blanchard 237 (determined as R. semisetosus) . 



Ruhus flagellaris X nigricans. This was collected by Mr. 

 Bicknell, who included it in R. nigricans. The following speci- 

 mens so named I refer to the hybrid instead. 



Massachusetts: Little Neck, Millbrook Swamp and Long 

 Pond, Nantucket Island, 1910, Bicknell X,XX, XXX. 



Ruhus nigricans X procumbens. This was also recognized as 

 a hybrid although he did not describe the same. The following 

 specimens belong to it: 



New York: East Hempstead, Long Island, 1910, Bicknell 16; 

 Jamaica, 1906, Bicknell 18. 



Connecticut: Plainville, 1904, Andrews 55; Southington, 

 Andrews 54, 57, 5^, 59, 62. 



Vermont: Londonderry, 1903, Blanchard 245 (referred doubt- 

 fully to R. vermontanus) . 



Nova Scotia: Macoun 51425; Sable Island, Macoun 21 193- 



Ruhus nigricans X vermontanus. Ruhus vermontanus viridifolius 

 h^s glandular hispid inflorescence and I therefore believe it 

 contains some R. nigricans blood in it. I therefofe regarded it 

 as a hybrid. Many specimens referred to R. setosus by Blanchard 

 belong here: 



Vermont: Marlboro, 1902, Blanchard 191; Woodstock, 1910, 

 Britton; Stockbridge, 1897, Eggkston; West Windham, 1904, 

 Blanchard 59, set i; Stratton, 59, Blanchard, set 2; Rutland, 1899, 

 Eggleston 1228.
