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 JMienchu Hsien, a town on the north-west corner 

 of the Chengtu Plain, Cryptomeria occurs in some quantitj^; 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 arcuaiis 

 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 oj Western China, No. 174.
