 but recently introduced, in some of our 

 streets, at- Eosedale, and many other places 

 in the vicinity.

 cia, Monadelphia, Linn. Cones erect, cylin 

 drical ; scales not thickened at the tip. Leaves 

 more entirely 2-rowed than in abies. 



1. P. BALSAMEAjj&mnceiw. Leaves solitary, 

 silvery beneath, about a half inch long, some 

 what recurved. Cones violet-colored, four 

 inches long, a half inch broad, tapering to 

 wards the top. Seed about half the size of the 

 silver fir. Balsam fir. Native of the Northern 

 and Middle States. 



A well known and widely cultivated spe 

 cies. It is readily distinguished from the 

 silver fir by the cones, and easily by practice 

 in the foliage and habit of the tree. It is a 

 very pretty conical tree while young, but be 

 coming very meagre-looking by age, unless 

 in a very deep loam. It does well in most 

 soils, or situations that are not too wet or stiff.
