PINUS RESINOSA, AIT. 11 



about | inch long, tapering to a sharp point, reddish-brown, 

 invested with rather loose scales. 



Foliage leaves in twos, from close, elongated, persistent, and 

 conspicuous sheaths, about 6 inches long, dark green, needle- 

 shaped, straight, sharply and stiffly pointed, the outer surface 

 round and the inner flattish, both surfaces marked by lines 

 of minute pale dots. 



Inflorescence. Sterile flowers clustered at the base of the 

 season's shoots, oblong, i-f inch long : fertile flowers single 

 or few, at the ends of the season's shoots. 



Fruit. Cones near extremity of shoot, at right angles to 

 the stem, maturing the second year, 1-3 inches long, ovate to 

 oblong conical; when opened broadly oval or roundish ; scales 

 not hooked or pointed, thickened at the apex. 



Horticultural Value. Hardy in New England ; a tall, dark- 

 foliaged evergreen, for which there is no substitute ; grows 

 rapidly in all well-drained soils and in exposed inland or sea- 

 shore situations ; seldom disfigured by insects or disease ; 

 difficult to transplant and not common in nurseries. Prop- 

 agated from seed.

Pinus sylvestris, L. 

 Scotch Pixe (sometimes incorrectly called the Scotch fir).
