broad, with five short, rounded petals and pointed, reflexed calyx- 
lobes; stamens many, inserted on a disk at the base of the calyx.

DEWBERRY 
Rubus villdsus, Ait. 
(Ribus procimbens, 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 
places. 
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 
length, with many small erect fruiting
