378 THE EVOLUTION OF OUR NATIVE FRUITS 



stems densely clothed with very slender though slightly bent 

 prickles; leaflets usually large, ovate to oblanceolate, pointed, 

 scarcely shining, very strongly toothed; fruit reddish black. In 

 bogs throughout the northern states and southward to Florida 



and Arkansas. It is distinguished 

 by a light cast of foliage and 

 yellowish prickles. In many cases 

 it looks as if it were a hybrid 

 between a blackberry and red 

 raspberry, and has, in fact, been 

 taken for such. It has ordi- 

 narily, however, been con- 

 founded with Ii. hispidus, with 

 which it has little in common. 

 The long, slender, and seal - 

 tered bristles and diffuse, open 

 habit distinguish it from its 

 allies.
