ROSACEAE (ROSE FAMILY) 217 



often more than two inches broad, occasionally solitary but usually 

 growing in open corymbose clusters. Hips globular, smooth, about a 

 half -inch in diameter, crammed with hard, hairy achenes. (Fig. 156. ) 



Means of control 



If the plants are young and few, grub out the colonies, securing, 

 if possible, every shred of the rootstocks ; in ground rankly infested, 

 cut the stalks from the rootstocks with a very sharp-bladed plow 

 in the hot days of July. New shoots will promptly appear, which, 

 at intervals of not more than two weeks ten days would be 

 better must be disked, or cut off with a sharp and broad- 

 bladed cultivator, in order to keep leaf growth from feeding the 

 rootstocks. Next season put in a cultivated crop of which the 

 tillage will constantly keep the shoots cut off, and so starve the 

 underground stems. 



WILD BLACK CHERRY 



Primus serotina, Ehrh. 



Native. Perennial. Propagates by the stones, or pits. 



Time of bloom : May to June. 



Seed-time: A drupe, ripe in August and September. 



Range: Nova Scotia to Florida, westward to the Dakotas and 



Arizona. 

 Habitat : Woodlands, and also common along fence rows, roadsides, 



and waste places. 



The Black Cherry is often a large tree and a most valuable one 

 to dealers in fine cabinet-making woods. It has reddish brown 

 twigs, with somewhat bitter, aromatic, inner bark. The leaves are 

 somewhat thick in texture, smooth and shining on the upper side, 

 broadly lance-shape to oblong, taper-pointed, the teeth incurved 

 and short. The flowers are white and grow in elongated terminal 

 racemes ; the fruits which follow are purplish black drupes, 

 slightly bitter but pleasant to the taste. 



It is not the mature tree that must be placed .on the list of noxious 

 plants, but its numerous progeny of young shoots which spring 

 up everywhere about the country. Birds are very fond of the 

 juicy fruits and eat great quantities, voiding the stones along 

 fence rows and telephone lines, with the result that those land-
