THE CYPRESS SUB-FAMILY. 327 



compressed ovules. Cones small, with coriaceous, smooth, 

 orbicular, persistent scales. Seeds with an emarginate, 

 membranaceous wing. Leaves persistent, small, scale-like, 

 appressed, and imbricated in four rows. 



This handsome new genus is from Japan, where it was 

 first seen and described by Dr. Siebold, who named it 

 from its resemblance to the genus Thuja. 



1, T, dolabrata, Siebold Syn. Thuja dolabrata, Thun- 

 berg. Leaves short, ovate, obtuse, flattened, or slightly 

 convex above, thick, imbricated, dark-green color above, 

 and glaucous beneath. Branches spreading, verticil! ate, 

 drooping at the extremities ; with numerous, compressed, 

 biserial, branchlets. Cones quite small, ovate, with jagged 

 edges, sessile ; scales reflexed, and wedge-formed. 



The great rarity of this- is, as yet, a serious obstacle in 

 the way of an extensive trial. Plants are being slowly 

 introduced into our collections, and -we trust soon to be 

 able to record their suitability to our climate. A. fine 

 plant of this T/iuiopsis in the beautiful collection of Alfred 

 Cope, of Germantown, Pa., has succeeded quite satisfac- 

 torily for several years in a shaded situation, but how it 

 might grow on an open and exposed spot, we are unable 

 to judge. 



It forms a drooping, conical tree, about 40 or 50 feet 

 high, with rather an open head ; the branches extending 

 vertically, and drooping at the extremities. The form 

 is even and regular, with foliage of a remarkably rich 

 dark-green color, which is heightened by a peculiar 

 glossiness on the upper surface, and a glaucousness be- 

 neath. The great beauty of this tree has caused it to be 

 very popular in China and Japan, where it is grown exten- 

 sively in pots, and is also used for avenues. 



It delights in a shaded and rather moist situation, which 

 should be borne in mind by cultivators when selecting a 

 location here. 



This splendid tree is entirely hardy in England, and we
