Hab. Hei-lung-t'an prope Yunnan, leg. Sh. Kawai, Jan. 1917. 



Near C. japonica D. Don; but differs from it in having much 

 shorter secondary scales with much shorter teeth. 



It is rather questionable whether the tree truly wild in the 

 above given locality. Yet, it is said th'it it really exists in a 

 primeval forest near Tin-an dji't^c). Prof. Kawai has an opinion 

 that, though the present tree may be identical with the Japanese 

 Cryptomeria, the two (Chinese and Japanese) should decidedly 

 be originated from different stocks, one from the Chinese origin 

 and the other from the Japanese] Mr. G, II. Wilson has the 

 same opinion. Moreover, the present plant has very different 

 aspects from the Japanese species in the general features, as 

 I'rof. Kawai assured me from his observations on the spot. As 

 the coniferae is itl general very local, I am forced to the con- 

 clusion that the Chinese species should be regarded aa distinct 

 from the Japanese, though the difference is rather slight as is 

 indicated by the much smaller secondary scales on the part of 

 the Chinese.
