48 THE CULTIVATED EVERGREENS 



appearance. The branches are usually horizontal and occasion- 

 ally somewhat divergent, and the habit picturesque. There are 

 fine specimens of this species in the Arnold Arboretum. It 

 is not particular about soil conditions. A very decorative form 

 or variety with silvery-bluish leaves appears amongst seedlings 

 occasionally. 



The tree sometimes called the Macedonian white pine, 

 Pinus Pence, from the mountains of southeastern Europe, 

 bears a general resemblance to the Swiss stone pine in its 

 pyramidal habit. It is slow growing and quite hardy and well 

 adapted to small ornamental grounds. It appears more subject 

 to the attacks of the pine-leaf scale than any other white pine. 



The Bhotan white pine, Pinus excelsa, from the Himalayas, 

 is characterized by handsome long leaves frequently eight inches 

 in length. The branches are horizontal, drooping, and oc- 

 casionally divergent. A well-developed individual on the 

 border of a lawn is an object of much beauty. A fine specimen, 

 fifty feet in height, is now standing on the grounds of the 

 Genesee Valley Club, East Avenue, Rochester, New York. 

 A number of individuals have been lost from the stems being 

 punctured by sapsuckers, and they appear to "bleed to death." 

 There is no remedy for this, except, perhaps, to destroy these 

 birds and this is not permitted by law. 



The Mexican white pine, Pinus Ayacaliuite, native in 

 Mexico, has long leaves and bears some resemblance to the 

 Bhotan white pine. The horizontal slender branches are some- 

 times inclined to droop, which gives the tree a most graceful 

 appearance. This pine has a reputation for being tender, but 

 it passed through the very cold winter of 1917 and 1918 a 

 little browned but recovered thoroughly. It should be planted 

 in a situation well protected from the sweep of the prevailing 

 cold winds and in moist, well-drained soil.
