DEWBERRY. The Dewberry is one of the most recent 

 acquisitions among garden fruits. As a cultivated fruit, 

 it is American, and the varieties are forms of native 

 species. It is distinguished from the blackberry chiefly 

 by its low, trailing habit, its method of propagating by 

 tips instead of suckers, and its few-flowered cymose 

 clusters. Four distinct species are found in cultivation. 

 (1) The northern Dewberry (Rubus villosus, Ait., until 



696. Deutzia Lemoinei (X 



lately known as R. Canadensis). In this species the 

 leaflets are thin and deciduous, the stems sparsely and 

 lightly prickly, and the flower-stalk slightly fuzzy but 

 not glandular. A well marked sub-type has been set off 

 from this species, comprising the Lucretia Dewberry
