DEWBERRY 



Rubus villdsus, Ait. 

 (Riibus procumbens, Muhl.) 



Other English names: Running Blackberry, Trailing Bramble. 



Native. Perennial. Propagates by seeds. 



Time of bloom: Late April to June. 



Seed-time : Fruit ripe in June in southern part of its range, in July 

 farther north. 



Range : Newfoundland and Ontario to 

 Lake Superior, southward to Vir- 

 ginia and Missouri. 



Habitat : Upland fields, meadows, and 

 pastures, fence rows, and waste 



A variety of this plant, much im- 

 proved by selection and cultivation, 

 comes to our tables as the delicious 

 "Lucretia Dewberry"; but the wild 

 bramble, sprawling itself over acres of 

 open uplands, is a pestiferous weed. 

 Birds are very fond of the fruits and 

 eat them to repletion, voiding the seeds 

 unharmed, so that prickly young Dew- 

 berry shoots get mown with the hay 

 of the meadows and keep turning up in 

 the most unexpected places. 



Stems prostrate, shrubby, very 

 prickly, six to ten or more feet in Plo- 153 _ Wild Dew berry 

 length, with many small erect fruiting (Rubus villosus). xi-
