BUSH-FRUITS 



Distribution. Sandy woods from southern New York and Penn- 

 sylvania, south to Florida, and west to Louisiana and Missouri. 

 This is represented in cultivation by the "Topsy," or "Child's 



Tree Blackberry." 



The Kew Index also rec- 



X &&EK ognizes a European species 



under the name R. cuneifolius 

 Merc., but it was published 

 since R. cuneifolius, Pursh., 

 therefore cannot stand. In 

 fact, the European name has 

 already been replaced by R. 

 splienoides, Focke. 



27. R. VILLOSUS, Ait. Low 

 Blackberry. Dewberry. 

 R. Canadensis, authors, 

 not L. 



Main stems shrubby, long, 

 trailing, rather sparsely and 

 lightly prickly; leaflets 3, 

 on both fruiting and young 

 canes (rarely pedately 5-7) ; 

 oval or ovate -lanceolate, 

 acuminate, or obtuse at base 

 of fruiting shoots, thin, 

 slightly roughened, sharply 

 and usually singly cut-ser- 

 rate, petioles and veins be- 

 neath often prickly; in- 

 florescence cymose, scarcely 

 extending beyond the leaves, 

 few-flowered ; peduncles 

 slightly pubescent but not 

 glandular; sepals tomertos > 

 within, often 3-lobed at tip, 

 the central lobe being long, 

 expanded and leaflike. 

 Distribution. Newfoundland to Virginia, and west to eastern 

 Kansas and central Minnesota. 



This species, with its varieties, forms the foundation type 

 to which the northern dewberries belong.
