WILD BLACK CHERRY 



Rum, Cabinet or Black Cherry. 



Prunus serotina Ehrli. 

 PadKs strotina (Ehrh. ) Agardh. 



HABIT — A medium sized tree 30-50 ft. in heig-ht with a trunk diameter 

 from S or 10 inches to 2 feet, becoming- much larger in the 

 middle and southern states: branches spreading often more or less 

 zigzag- forming an irreg"ular oblong head. 



BARK — On young trunks and branches smooth reddish-brown with 

 conspicuous oblong whitish horizontal lenticels, easily peeled off in thin 

 dark papery layers exposing the bright green bark below, becoming 

 with age very much roughened by irregular, close, dark, scaly plates 

 with upturned edges. 



TWIGS — Rather slender, smooth, reddish-brown, more or less covered 

 with a grayish skin easily rubbed off; crushed twigs with odor and taste 

 of bitter almonds. LENTICELS — numerous, pale, minute, rounded dots, 

 becoming horizontally elongated and more conspicuous on later growth. 

 lUTH — of recent growth, generally whitish. 



LEAF-SCARS — Alternate, more than 2-ranked, small, semi-oval to 

 inversely triangular, raist- d. STI PULE-SCA FiS — inconspicuous or appa- 

 rently absent. Bl'XL>LE-SCARS— 3, often inconspicuous. 



BUDS — Medium sized, ovate, blunt to sharp-pointed, about 4 mm. 

 long, smooth, bright reddish-brown, divergent or sometimes somewhat 

 flattened and apjiressed; terminal bud slightly larger than lateral buds. 

 BUD-SCALES — about 4 visible, broadly ovate, more or less rounded 

 and keeled on the back, of nearly uniform oolor or with darker edges, 

 sometimes partially covered with a grayish skin, similar to that usual on 

 the twigs. 



FRIIT — A drupe about the size of a pea, ripening in summer in 

 drooping elongated clusters. 



COMPARISONS — The Wild Black Cherry in its young growth 

 resembles the Chuke Cherry but grows to be a good sized tree and 

 develops a very ri.-ugh scaly bark. Further the lenticels tend to be 

 whitish and elongate horizontally with age. the buds are smaller and 

 redder and their scales are not white-margined. From the cultivated 

 Sweet and Sour Cherries the Black Cherry is distinguished by absence 

 of fruiting spurs, by smaller buds and by the character of its bark. 



DISTRIBUTIOX — In all scirts of soils and exposures; open places and 



rich woods. Nova Scotia to Lake Superior; south to Florida; west to 

 North Dakota. Kansas, and Texas, extending through Mexico, along the 

 Pacifie coast of Central America to Peru. 



IN NEW ENGLAND — Maine — not reported north of Oldtown (Penob- 

 scot county) ; frequent throughout the other New England states. 



AVOOD — Light, strong, rather hard, close straight-grained, with a 

 satiny surface, light brown or red. with thin yellow sapwood of 10-12 

 layers of annual growth; largely used in cabinet-making and the 

 interior finish of houses. The bark, especially that of the branches and 

 roots, j'ields hydrocyanic acid used in medicine as a mnic and sedative. 

 The ripe fruit is used to flavor alcoholic liquors whence one of the 

 common names.
