Hah. Prov. Musashi : Yoda in Koiwa-mura {T. Mahino\ May 11, 

 1890, Aug. 1893, Aug. 7, 1894, Aug. 1902; S. Renol herb. 8c. Coll. 

 Imp. Univ. Tokyo, Sept. 1890); Prov. Hitachi: Nasaka-ura in N.uuekata- 

 gori (Y. SuzuJd\ July 15, 1902). 



Rare. In ours, the flower is normally expanded and the petals are 

 not calyptrately connivent. It was discovered by me in May 11, 1890, 

 and July, 1891, in flower, in stagnant water of a small pond about 

 rice-field in Yoda at Koiwa-mura on the river side of Yedo (a main divis- 

 ion of R. Tone), about 7 miles east of Tokyo. Its occurrence in this 

 country is very interesting for the investigation of Japanese Flora.
