the same rule as the leaves. Lastly, the seeds in the Japanese 

 plant are nearly equal to the scales in length, and the wing of the 

 seed is nearly entire, while in T. gigantea the seeds are distinctly 

 shorter than the scales, and the wing is deeply notched. 



Mr. Syme (in litt.) points out to me that the bark of the young 

 Japanese plant is rough and shaggy, while that of the American 

 plant is quite smooth. To the same accurate observer I am in- 

 debted for the note that the male catkins of the Japanese plant 

 more nearly resemble those of T. dolabrata than they do those of 

 T. gigantea. Mr. Syme leans to the view that at some remote 

 period the Japanese imported T. gigantea from America, and that, 

 under cultivation and the general conditions of life in Japan, the 

 plant has taken on its varietal character.

This plant (the Chinese Arbor vitce of our gardens) is remark- 

 able for the great variations it presents in the shape of its cones, 

 its habit, foliage, &c. Hence, in gardens, a very large number of 

 seedling variations are met with, while other varieties represent 

 simply the immature or " larval " form of the species. 



Several of these forms are described by Endlicher ; others are 

 figured and described in Hoopes's ' Book of Evergreen*,' p. 331 

 Ac). The plant, though truly wild in Japan and in China, has
