THE BEST HARDY CONIFERS 123 



outline; microphylla, with loose ascending branches; 

 and pendula, with dense spreading branches pendent 

 at the extremities. 



The Carolina Hemlock (T. caroliniand) is native 

 of the Blue Ridge Mountains of north and south 

 Carolina, and of the southern Alleghanies where it 

 was discovered in 1850, by Professor L. R. Gibbes. 

 It was introduced into the Arnold Arboretum in 

 1881, where it grows freely and gives every promise 

 of being a most desirable and ornamental Conifer. 

 It is a smaller but a more graceful and beautiful 

 tree than its northern confrere. 



No trees make a better windbreak than do the 

 Pines, and on lawns and for avenues they are most 

 effective. The native White Pine (Pinus Strobus) 

 is one of the noblest of all Pines and needs neither 

 introduction nor eulogy here. Its confrere, P. mon- 

 ticola from western North America, is also perfectly 

 hardy and grows freely in this climate. So also does the 

 Foxtail Pine (P.flexilis), native of Montana, Nevada 

 and other parts of western North America. The 

 White Pine of the Balkan Peninsula (P. peuke), 

 which was discovered in 1839 but was not introduced 

 until 1864, is also quite hardy and grows well in this 

 country. It forms a narrow pyramidal tree densely 

 branched and heavily clothed with bright green leaves.
