picked fruit similar in every respect to that of T. orientalis, this 

 proving conclusively that it is only a distinct and well-marked 

 variety, and not a species as was at one time supposed. 



T, orientalis semperaurescens, — This is a neat 

 and dwarf bush, and which at no time loses its golden tinge, 

 the bright hue of the foliage rendering it conspicuous and 

 cheery even in the depth of the winter season. 



T, orientalis Zuccariniana, — Amongst small- 

 growing, neat-habited, and bright-foliaged shrubby, or rather 

 pigmy conifers, this is one of the best, and there are many 

 purposes to which it may be applied, especially in grounds of 

 limited extent. The branches are numerous and slender, 

 forming a dense, globose mass, and thickly-furnished with 

 bright green foliage, which colour it retains throughout the 

 year. It is a cheerful, pleasing shade of green, for which 

 the plant is justly remarkable ; and this, coupled with the 

 neat outline and ease of culture and propagation, should tend 

 to its increased cultivation. 



T, plicata, Don. {Sytiojiyms : — T. occidentalis plicata, 

 Loudon ; T. Wareana, Booth; T. gigantea plicata, R, Brown.) 

 North- West America. 1796. — In this we have a small- 

 growing tree of neat outline, but greatly resembling the 

 American arborvita^, from which, however, it may readily be 

 distinguished by the shorter branches and less straggling 

 habit of growth. The branchlets being numerous, give to the 

 tree, although the main branches are usually placed far apart, 

 a well-furnished and neat outline, and these in turn are fur- 

 nished with pairs of closely-appressed leaves, that are brownish- 

 green in colour. The cones are - of an inch long, with six 

 scales, and three of four seeds towards the middle. A 

 particular value must be attached to this species, from its 

 thriving well in cold and draughty situations where many 

 conifers could not succeed. Though sometimes placed as a 

 variety of T. gigantea and T. occidentalis, yet for garden 

 purposes T. plicata is amply distinct, whether in habit, foliage 

 or fruit.
