Hab. : In deep water. Provs. Mikawa, Shinia. 



Remarks : From the resemblance of the external appearance 

 of the present plant with Prionitis Andersoniana Eaton I formerly 

 referred it to Prionitis. It, however, resembles, on one hand, to 

 Carpopdtis data Okam. (illustrated on the next plate) in the sub- 

 stance, structure and sporophylls ; while, on the other, to C. angiista 

 (Harv.) Okam. in the habit, substance and structure. As consequence 

 I now put the plant in question in Carpopdtis.
