244 BUSH-FRUITS 



of the obstacles to the successful cultivation of this 

 species is the variable sexual character of its blos- 

 soms. If pistillate varieties are introduced, they 

 must of necessity be planted with perfect or staminate 

 plants to insure fruit production. It is doubtful, also, 

 whether even the perfect -flowered sorts would prove 

 fully self -fertile in a species with such a strong ten- 

 dency to separate sexual development. Until these 

 points are more fully determined, it appears to be a 

 wise precaution, if this species is to be planted at all, 

 to plant more than one variety together. 



VII. THE NORTHERN DEWBERRIES 

 Eubus invisus, R. villosus and Varieties* 



Bartel (Eubus invisus). This was the first named variety of 

 dewberry. It was brought to notice sometime in the 70 's by 

 Dr. Bartel, of Huey, Clinton county, 111. The plants are said 

 to have appeared in an old cornfield on his farm, and the large 

 size of the fruit led him to offer them for sale. The fruit is 

 described as large, rich, juicy, slightly acid, but not so sour as 

 the blackberry, and sufficiently solid to bear shipping well. 



Colossal. A sort offered by L. L. May & Co., St. Paul, Minn. 



Geer (Eubus villosus). A variety discovered by F. L. Wright, 

 in a wood-lot belonging to a Mrs. Geer, of Plainfield, Living- 

 ston Co., Michigan. It was first brought under cultivation in 

 1887. Said to be productive, though small in fruit. 



General Grant (Eubus invisus}. Introduced by Charles A. 

 Green, of Rochester, N. Y., in 1885 or 1886. It came from M. 

 W. Broyles, somewhere in Tennessee. It possessed little value, 

 and never became prominent. 



Latimer Seedling. Mentioned as on trial at the Geneva 

 (N. Y. ) Experiment Station. Received from J. W. Latimer, 

 Pleasanton, Kansas. 



*A full account of the eastern dewberries is given by Bailey in Bulletin 34 

 of the Cornell University Experimental Station, which is freely drawn upon in 

 making up the following list.
