5G6 EVERGREEN TREES A .\ I) SHRUBS. 



The Globe Arbor-Vit^. Thuja globosa. — This is a pretty 

 dwarf shrub, very round and compact, and quite a favorite in the 

 neighborhood of Phihidelphia ; three to five feet high. 



The Tom Thumb Arbor-Vit^e. Thuja mmimal — A roundish 

 or oblate dwarf, of compact habit, which originated in the nurseries 

 of Ellwanger & Barry, Rochester, N. Y., and is highly recom- 

 mended by them. Height three to four feet. 



The Nootka Sound Arbor-Vit^. Thuja plicata. — This is a 

 native of the Pacific slope, and differs from the indigenous arbor- 

 vitae of the eastern States in the more vertical and flatter arrange- 

 ment of its foliage plaits, and its shorter and stouter young wood. 

 Very like the Siberian in the color of its leaves, but less rich in 

 the massing of its foliage : quite hardy. 



The Gigantic Arbor-Vit^. Thuja gigantca. — A tree of the 

 largest size, growing on the banks of the Columbia river, where it 

 grows upwards of one hundred feet in height. It is said to de- 

 velop into " a fine, umbrella-shaped top, and picturesque head." 

 This form is unusual among evergreens, and so desirable, that, if it 

 proves a characteristic of the tree, it must become popular for 

 that reason alone. Hoopes, however, believes that it will not prove 

 hardy, though it has not been tested long enough to determine this 

 point fully. 



The Chinese ARBOR-ViXiE. Biota orientalis. — This is a little 

 beauty when quite young, and marked by a warmer-toned green, 

 and a finer quality of foliage, than the common American. It is 

 also less regular in outline, and the foliage breaks apart into masses 

 rather vertically. Unfortunately it has not proved hardy, and is so 

 often injured by winter and summer, that instead of growing more 

 beautiful as it approaches maturit}', it becomes less comely, and 

 after a half dozen years trial is generally pronounced scrawny. 

 There is a tree in the Bartram garden south of Philadelphia, 

 growing in a good exposure, which is twenty feet high, nearly as 

 broad, and with a trunk ten inches in diameter ; but it is decidedly 

 a meagre-foliaged tree.
