PINACEAE. — THUJA 53 



All the trees of Cryptomeria we have seen in China were planted, yet it occurs 

 in such remote places in the far west of Szech'uan that one strongly suspects that 

 it is native of this region. For example: on the lower slopes of the Chiu-ting- 

 shan, two days' journey west of Mienchu Hsien, a town on the north-west corner 

 of the Chengtu Plain, Cryptomeria occurs in some quantity; it is also found on the 

 mountains to the west of Kuan Hsien. It would appear highly improbable that 

 these trees or their parents had been introduced to these remote, sparsely popu- 

 lated regions from Japan or eastern China. 



This tree was first discovered by James Cunningham in the Chusan Islands, 

 and a specimen collected by him is figured in Plukenet, Opera IV. t. 386, fig. 3 

 {Amalt. 69) (1705) under the name of Cupressus cheusanensis, juniperinis arcuatis 

 foliis, etc. 



It is the " Kung-ch'io Sung " (Peacock Pine) of the Chinese. 



A picture of this tree will be found under No. 690 of the collection of Wilson's 

 photographs and also in his Vegetation of Western China, No. 174.
