THE PINE SUB-FAMILY. 193 



it is also very dense and compact in growth, and remark- 

 ably graceful in the arrangement of its branches. The 

 main body of the tree is usually straight, with a gradual 

 tapering upwards, and covered with a smoothish, thin 

 bark. 



We have hopes of being able to acclimate this species, 

 the section of country from which it comes being such as 

 to warrant the belief that it will be hardy. In England 

 it is represented as being " entirely hardy, and very much 

 resembling in general appearance the Hemlock Spruce." 



Some late English writers have confounded it with the 

 following species, A.. Williamsonii, but it is very distinct 

 from this in many leading characters. Timber, white, 

 soft, and almost devoid of turpentine. 



19. A. Tsuga, Siebold < Zuccarini. Syn. Pinus Tsuga, 

 Antoine & Endlicher; Tsuga Tsuja, Murray; T: Sieboldii, 

 Carriere. Leaves, from 6 to 10 inches long, persistent, ap- 

 proximated, alternate, sub-distichous, linear, emarginate, 

 obtuse, or rarely acute, smooth, coriaceous, dark green 

 above, with a white line on each side of the midrib below. 

 Cones, scarcely 1 inch long, elliptic, or sub-elliptical, soli- 

 tary, terminal, obtuse, quite persistent ; with coriaceous, 

 imbricated, pale brown scales; bracts, truncate, rather 

 broad, irregularly bifid, closely appressed. Seeds, small, 

 ovato-rhomboidal, somewhat compressed, with a pale, fer- 

 ruginous, membranaceous wing. 



A small Spruce, rarely exceeding 20 or 30 feet in height, 

 and reminding one of a small Hemlock Spruce, both in 

 habit and general outline, and in fact they are nearly 

 allied. There also exists a close relation between it and 

 A. Brunoniana. 



It has a very erect trunk, with a dark brown bark, and 

 numerous, pale, slender branchlets. 



This new Spruce is found in the northern provinces of 



Japan, in the mountainous parts of Mutsu and Dewa, but 



is quite rare ; Siebold only noticing it in the gardens and 



shrubberies surrounding the temples. The wood is yellow-
