" Varieties of Pinus sylvestris. 

 Var. 1st. The common variety, well known by 

 its branches forming a pyramidal head, the leaves 

 marginated, of dark-green colour, but little glaucous 

 underneath, the cones being considerably elongated 

 and tapering to the point, and the bark of the trunk 

 very rugged. This variety seems short-lived, becom- 

 ing soon stunted in appearance. 



" Var. 2d, Distinguishable from the former by 

 disposition of branches, which are remarkable for ho- 

 rizontal disposition and tendency to bend down- 

 wards close to the trunk. The leaves are broader 

 than var. 1st, and serrulated, not marginated ; 

 leaves are distinguishable at a distance by their 

 much lighter and beautiful glaucous colom*, the bark 

 not so rugged as var. 1st, and the cones thicker and 

 not so much pointed, and also smoother. This tree 

 seems a hardy plant, growing freely in many soils : 

 this variety may be named Pinus horizontalis. Var. 

 1st. much more general than var. 2ld, and also sooner 

 comes to seed, which is also easier gathered from the 

 position of the branches. 



" Var. 3d, Is of a still lighter colour than var. 2d, 

 being of a light glaucous hue, approaching to a sil- 

 very tint ; its branches form, like var. 1st, a pyrami- 

 dal headj but it differs remarkably in its cones from
