been collected at Satporo by Dr. K. Miyabe in June 1897 and 

 also at Hattarapet near Satporo by the writer in June 1909. 

 It is quite possible that the present form has a wider range of 

 distribution than we know at present. 



III.— Parnassia alpicola and P. simplex. 



Parnassia alpicola was published in 1904 by Mr. T. Making 

 who drew up a description from the specimen collected on Mt. 

 Shirouma and sent to bimlV In 1911 when Dr. B. Hayata 

 worked out the Japanese species of Parnassia he recognized four 

 species as natives of Japan, namely P. palustris L., P. foliosa 

 Hook et Thoms., P. alpicola Mak., and P. simplex Hay. This 

 last named plant was published by him in the following year, 

 after a careful comparsion with P. alpicola, the most closely 

 related species. 2 ' 



According to Dr. Hayata his new species can be distinguished 

 from P. alpicola by having the stems generally solitary, petals 

 very much smaller, staminodes usually entire, apiculatc or very 

 shortly 3-branched. On the other hand, P. alpicola possesses, 

 according to the same botanist, stems generally fasciculate in 

 threes or rarely solitary, petals much larger, staminodes pectinate 

 with 3-4 setae at the apex. Another important distinguishing 

 point is that the ovary of P. alpicola is conical,' 1 while that of 

 P. simplex is conico-ovoid. 



The writer has had recently an opportunity of closely 

 examining numerous specimens of P. alpicola from Mt. Shirouma 

 and of P. simplex from Mt. Tateyama and Mt. Iidc, including 

 those specimens which Dr. Hayata had at his disposal. It was 

 discovered that Dr. Hayata made a comparison of these two 

 species on specimens representing not the same stage of develop- 

 ment. Those of P. simplex were fully ripe, while those of /'.
