Rubus proaimhens X rectirvans. Many specimens from Con- 

 necticut resemble R. prociimhens closely, but are more pubescent 

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

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



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

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



Massachusetts: Southwick, 1903, Blanchard 255. 



Ruhus pergratus X proctimhens. Rubus recurvicaidis Blanchard 

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

 bining characters of both. I have seen no specimens except 

 those distributed by Mr. Blanchard. 



Rubus canadensis X procumbens. Rubus recurvicaidis inar- 

 matus stands to R. canadensis as R. recurvicaidis 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. 



Rubus hispidus X procumbens. 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 90 j. 



Rubus 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. & E. G. Britton & A. M. Vail. 



Rubus Enslenii X procumbens, 



Rubus Baileyanus X Enslenii, 



Rubus Enslenii X flagellaris, and 



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

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

 38: 130-131. 1911.
