Description, S^c. A tree 40 ft. or 50 ft. high, with 

 the habit of P. sylvestris, but with a much more 

 branchy head ; and readily distinguished from that 

 species by the young leaves not being glaucous, 

 and by the leaves generally being more straight 

 and rigid, slightly serrated at the margins, and 

 with shorter sheaths. The leaves are also of a 

 paler green, both when young and full grown, so 

 tliat the tree, when of large size, has notiiing 

 of the gloomy appearance attributed to the Scotch 

 pine. Tiie cones are of a liglit yellowish brown 

 colour, without footstalks ; and they are generally 

 in whorls of '6 or 4 together, pointing horizon-
