THE PLUM FAMILY (AMYGDALACE^E) . 



Defects caused by sapsuckers have been observed in the wood of 

 seven species of this family. Not all these species have great eco- 

 nomic value, but the wild black cherry furnishes one of our most 

 costly woods. The blemishes in it are typical of those in this family, 

 and they are sometimes so serious as to ruin the wood for any orna- 

 mental use. 



Wild black cherry (Padus serotina). — In specimens from south- 

 ern Arizona (A. A. and 

 A. M. 188) sapsucker 

 defects vary from small 

 to large black checks 

 accompanied by little 

 stain. Specimens from 

 Randolph County, W. 

 Va. (H. 6801a), show 

 large stains up to 1^ 

 inches long and vary- 

 ing from yellowish 

 brown to black about 

 the healed wounds. 



The injuries evi- 

 dently do not heal 

 readily, as cavities sur- 

 rounded by gnarly 

 growth are formed. 

 Defects in cherry, 

 which is used almost ex- 

 clusively for ornamen- 

 tal purposes, are very 

 objectionable. Such 

 as are here described would certainly lower the grade of lumber, 

 causing a loss of perhaps 75 per cent from the best selling price. 



Species of Amygdalace^: blemished. — Hog plum, wild goose 

 plum, garden plum (F.), bitter cherry, western chokecherry, wild 

 black cherry, and islay. 



THE SENNA FAMILY (CJESALPINACE^). 



Blemishes caused by sapsuckers have been noted in but one species 

 of this family — the honey locust.
