A MANUAL OP THE CONIFER*. 



Biota orientalis. — A low tree or shrub of pyramidal, but very 

 frequently of columnar habit, attaining a height of from 18 to 25 

 feet in its native country, and seldom more in Europe under culti- 

 vation. It is easily distinguished from the American Arbor Vitss 

 by its denser habit and foliage of brighter green. It is one of 

 the commonest and most useful of garden shrubs. 



Biota orientalis argentea differs from the common form in 

 having many of its branchlets creamy-white. The variegation is 

 rather inconstant, and not unfrequently disappears altogether in a 

 few years. 



Biota orientalis aurea. — A dwarf, dense, globose shrub, having 

 its first growth in -early spring, of a rich golden-yellow, which 

 gradually changes by age to the bright green of the species. 



This valuable variety originated in the Nursery of Mr. "Waterer, at 

 Knap Hill. It is generally known under the name of Thuia aurea, 

 and is one of the most ornamental and popular of all the varieties of 

 Biota orientalis. 



Biota orientalis aureo-variegata has about one-half of its 

 branchlets and foliage light yellow. It resembles the common 

 form in habit, and is quite distinct from the preceding. 



It originated in the Nursery of M. Dauvesse, at Orleans, in Prance.
