Rubus setosus Bigelow is similar to the bristly dewberry, 

 but has very glandular pedicels and sepals while the former is 

 usually glandless. This is much less common than the bristly 

 dewberry (R. vermontanus.) 



BLACK DEWBERRY. RubuS villostiS L. 



This species occurs in sandy soil in similar locations to the 

 white pine and is more abundant farther south. It is readily 

 recognized by its trailing habit, five thin leaflets, one to four flow- 

 ers in the cluster, and round, large druped, sweet berries. 



SWAMP DEWBERRY. Riibiis liispidus L. 



This pretty trailing vine of the lowland swamps is easily 

 know by the dark-green, shining, thick leaves with three leaflets 

 which usually remain green throughout the winter. The berries 

 are very small and sour. 



THE CULTIVATED BERRIES. 



These berries are esteemed more highly for their fruit in 

 this country than in Europe. The European red raspberry has 

 long been cultivated in that country and was early introduced 

 into the United States, but it has been practically driven out by 

 the American cultivated berry, which is more hardy and ripens 

 its fruit in a shorter time. The Cuthbert is one of the leading 

 American red raspberries. The black raspberry is even more 

 important commercially than the red, since it is dried very ex- 

 tensively. The Ohio and the Gregg are standard cultivated 

 forms of the black raspberry. The Shaefer and the Gladstone 

 are supposed to have sprung from the hybrid, Rubus neglectus. 



The blackberries and dewberries are an American product, 

 the first cultivated blackberry, the Dorchester, being produced 

 in 1841. Some of the best varieties have been evolved from the 

 high-bush blackberry and its allied forms. Here belong the
