Flovers monoscious, solitary, and terminal ; the male catkins 

 cylindrical, the female somewhat globular. 



Cones ligneous, sub-globular, and composed of eight or ten 

 valvated, opposite, imbricated scales. 



Scales wedge-shaped, leathery, valvate, more or less orbicular, 

 concave, smooth, and persistent. 



Seeds five at the base of each scale, orbicular, compressed, and 

 free, with a membranaceous wing on each side. 



Leaves scale-like, opposite decussate pairs, regularly and closely 

 imbricated in four rows, flattened on the upper and under surfaces. 



Name derived from Thuya, the Arborvita?, and opsis, like — ■ 

 resembling the Arborvitae. 



Only one majestic evergreen tree, found in moist situations in 

 Japan, now belongs to this genus ; formerly the Chamsecyparis nutJca- 

 ensis was often, and is still sometimes, called Tliuyopsisborealis.

Thuyopsis dolahrata was first made known to Europeans by Thun- 

 berg, in 1784. The first living j^lant received in England was sent to 

 Messrs. Yeitch's Exeter nursery by Mr. Thomas Lobb, in 1853, from 

 the Botanic Garden at Buitenzorg, in Java. This plant arrived in a 

 weak condition, and all eflbrts to save it proved fruitless. In 1855 

 a plant was received at the Botanic Garden at Leyden from 

 Dr. Siebold {Gardeners' Chronicle, 1855, p. 241) ; but it was not till 

 1861, when Mr. J. G. Yeitch, and later in the same year Mr. Robert 

 Fortune, sent plants and seeds to the Chelsea and Ascot nurseries 

 respectively, that this fine Conifer became generally distributed 

 (Yeitch, Manual of Conif.). 



Tliuyopsis dolahrata, planted in 1879, has attained a height of 11 feet. 

 Plants with top-shoot are not so rare here as in many parts of Germany.

The commonest name for this variety seems still in nurseries to be 

 Thuyopsis dolahrata laetevirens.
