ber of species identical with, or closely allied to, those already known 

 to inhabit Kamtchatka and North-west America. This Dr. Gray 

 found to be the case ; {C and at the same time it has brought to view an 

 equal number of Eastern United States forms, no insignificant portion 

 of which are specifically identical." We regret that " another and per- 

 haps a larger collection of Japanese plants " could not at the same 

 time have been published, we mean that made by "the excellent and 

 most assiduous collector, Mr. Charles Wright, in the North-Pacific Ex- 

 ploring Expedition, under Commodore Rogers." 



The work, of twenty-eight quarto pages, makes known forty new spe- 

 cies and one new genus : of these thirteen are Varices, elaborated by 

 Dr. Boott, while Mr. Daniel C. Eaton determined the Ferns, Mr. Sul- 

 livant the Mosses, and Dr. Harvey the Aigse. 



It is not a little interesting to see how many European, and even 



English plants, are found to be natives of Japan, and these scarcely 

 likely to be introduced by accident or design ; viz. Ranunculus sceleratus, 



H. repens ?, Caltha palust?is, Pceonia officinalis, Herberts vulgaris, Cheli- 

 donium majus, Nasturtium palustre, N. officinale, Tiirritis glabra, Arabis 

 hirsuta, A, alpina, var. ?, Arabis lyrata, Cardamine impatiens, Draba

Native specimens of the JDicentra or Bielytra (De Cand.) spectabUis 

 prove that that most lovely plant is a native, not of China proper, as 

 many have supposed (see the remarks in Bot. Mag. at tab. 4458), but 

 of North Japan, and this accounts for its being so hardy with us.
