The Common (British) Evergreen Cypress. Cupressus 

 sempervirms. — A tree with dark foliage and fastigiate habit, re- 

 sembling in mode of growth the Lombardy poplar, though not 

 quite so slender. This tree, so generally grown throughout England 

 and middle Europe, is found utterly unsuited to our middle States. 

 Sargent seems to have given up hope of acclimating any of the 

 numerous English and Continental varieties. We shall, therefore, 

 make no mention of them. The species which now give promise of 

 hardiness, in the middle and southern States at least, are the new 

 varieties from the Pacific slope. These are : the Lawson cypress, 

 C. Lawsoniana, and the Nootka Sound cypress, C. nootkaensis, more 

 generally known by the botanical name, Thuiopsis borealis.
