GENUS PINUS. 89 



P- Lambertiana, Douglas. The Sugar Pine. 

 California, Oregon. 1827. With its giant proportions, 

 distinctly glaucous green foliage, and large and beautiful 

 cones, this species must be considered as one of the most 

 ornamental of the genus. In England it has not usually 

 succeeded well, although that there are numerous beautiful 

 specimens would be folly to deny. It is of erect growth, the 

 trunk being heavy and well formed, while the branches have 

 a distinct horizontal, or, perhaps more correctly, downward 

 tendency in growth, with the tips upturned. The slender 

 leaves, arranged five in a sheath, are about 4 inches long, 

 of a distinct shade of green, and for the greater part tufted 

 near the branch tips. The cones are strikingly handsome, 

 being in home-grown specimens from 12 inches to 14 inches 

 long, cylindrical of shape, and with the bracts loosely arranged. 

 Two seeds are beneath each scale, these being J of an inch 

 long. The bark is light grey in colour, resembling, as indeed 

 does the whole tree, the better known P. strobus. 



P, LariciO,^ Poiret. Corsican Pine. Dalmatia, Servia, 

 Thessaly. Whether in an ornamental or economic sense this 

 must be considered as one of, if not the most, valuable species 

 that is cultivated in this country. It is of rapid growth, 

 succeeds well in many classes of soils, even in that of gravelly 

 composition, and produces a large quantity of excellent 

 timber. In point of ornament this pine occupies a front rank, 

 the finely rounded and perfectly straight trunk and thickly 

 foliaged branches being different to almost every other 

 species. The leaves are glaucous green, about 4 inches long, 

 and produced in twos ; while the light yellow cones are 

 3j inches long, by i^ inches in diameter, and tapering quickly 

 to the point. The upright habit, narrow branch spread, and 

 finely formed trunk, are points of special recognition, and 

 which make this species so well suited for general forest 

 planting. There are many varieties, the following including 

 the best known and most useful.
