Specimens of this plant were collected by Mr. Samuro Okubo and myself 

 on the summit of Mt. Chokai in the province of Ugo,on July 28, 1887. 

 Although I have a number of specimens, none of them have fruit. 



In habit this plant somewhat resembles Arenaria inerckioides^ maxim. 

 (Mel. Biol, vol. xii., p.. 721.). Prof. Miyabe of Sapporo was kind enough to 

 lend me the only two specimens in his possession, from which M. Maximowicz 

 described the species. These specimens can be at once distinguished from my 

 plant; for the stems of the former are more robust than those of the latter, and 

 the leaves of the former are deflexed and thicker than those of the latter.
