IMPORTANT COMMERCIAL TREES 



Pine 



The four species of pine in Delaware, in order of their importance, 



are : loblolly, spruce, shortleaf , and pitch. Loblolly and pitch pines are 

 not distinguished locally and are called long-chat or foxtail pine. Short- 

 leaf generally goes by the name of "old growth" pine, but large clear- 

 boled trees of loblolly go by the same name. Shortleaf and spruce pine 

 when young are usually not distinguished locally, and both are called 

 indiscriminately spruce pine or * * short-leaved ' ' pine. In other States 

 spruce pine is usually called jack or scrub pine. 



Loblolly pine is considered at length in another portion of this re- 

 port. Pitch pine is often hard to distinguish from loblolly; both spe- 

 cies have needles four to eight inches long and three to four in a sheath, 

 but pitch pine has a decidedly broad ovoid cone, while the cones of 

 loblolly are oblong and long. Pitch pine occurs very infrequently in 

 Delaware and usually as single isolated trees in stands of loblolly ; its 

 most important occurrence in the State is along the seaboard in the 

 southwest. 



Spruce and shortleaf pines may be distinguished from pitch and 

 loblolly by the length of their needles, which in the case of both of the 

 former is only one to three inches; and they also have much smaller
