Leaves thin and sharply pointed, only about | in. long. A 

 seedling form.

 with pendent branchlets are not uncommon. 



Var. pumila. 

 A low-growing form after the style of var. 7iana.

P. sylvestris may be distinguished from other two-leaved 

 pines by its glaucous, twisted foliage, the reddish ii2)per trunk and 

 its characteristic habit in old age. 



The Scots pine has a wider distribution than any other pine, 

 being found wild throughout Europe and W. and N. Asia. It 

 occurs on a great variety of soils and in regions of the most 

 diverse climates. In the British Isles it is now only native in 

 Scotland where the remains of a few natural forests may still be 

 found. In ancient times it was widely spread in England and 

 Ireland, as is evident from the remains of logs, stumps of trees 

 and cones found in peat formations and in submerged forests.^ 

 It is now rapidly colonizing extensive tracts of heath land in the 

 South of England. 



Wood of excellent quality, moderately strong, resinous with 

 prominent resin ducts, and with well-defined annual rings ; heart- 

 wood and sapwood distinct. It varies in weight from 20-50 lbs. 

 per cubic foot, but is usually from 23-38 lb. per cubic foot. It is 

 easily worked, finishes with a smooth, satiny surface, holds nails
