Rhode Island: Rocky Point, 1906, Blanchard 96, set i. 



Rubus procumhens X recurvans. Many specimens from Con- 

 necticut resemble R. procumhens closely, but are more pubescent 

 and with the leaves of the floral branches more incised. These 

 I have regarded as hybrids with R. recurvans. They are : 



Connecticut: Southington, 1904, Andrews 29, 28, 41, 61, 

 37>34, 30; Plainville, 1903, Blanchard 222; Winsted Blanchard, 259. 



Massachusetts: South wick, 1903, Blanchard 23 j. 



Rubus pergratus X procumhens. Ruhus recurvicaulis Blanchard 

 seems to me a hybrid of R. pergratus and R. procumhens, com- 

 bining characters of both. I have seen no specimens except 

 those distributed by Mr. Blanchard. 



Rubus canadensis X procumhens. Ruhus recurvicaulis inar- 

 matus stands to R. canadensis as R. recurvicaulis does to R. 

 pergratus, and I believe also this to be a hybrid. 



Maine: Kennebunk, 1905, Blanchard 67, 69. 



Nova Scotia: North Sidney, 1907, C. B. Robinson 616. 



Ruhus hispidus X procumhens. This was first recognized by 

 Mr. Bicknell. The following specimens belong here: 



New York: Cypress Hill, 1905, Bicknell 74. 



Vermont: Londonderry, 1903, Blanchard, 246; Newfane, 

 1902, Blanchard 186. 



Nova Scotia: Boylston, 1890, Chas. Hamilton, 19985- 



New Jersey: Mt. Arlington, 1905, Mackenzie 1404; also 

 1904, Mackenzie 903. 



Ruhus Baileyanus X Enslenii. Also one of Mr. Bicknell's 

 hybrids. 



Massachusetts: Nantucket Island, 1908, Bicknell 52, 54, 55- 



Connecticut: New Haven, 1895, Helen Ingersoll. 



New York: Woodmere, 1904, Bicknell 56. 



District of Columbia: Riverdale, 1901, Steele. 



Virginia: Marion, N. L. Of E. G. Britton df A. M. Vail. 



Ruhus Enslenii X procumhens, 



Ruhus Baileyanus X Enslenii, 



Ruhus Enslenii X flagellaris, and 



Ruhus Enslenii X hispidus. Of these four hybrids, I have 

 seen none but Mr. Bicknell's specimens. See Bull. Torrey Club
