Potentilla tridentata var. Miyabe. 



Hah. Prov. Kushiro in Hokkaido: Mt. Meakan (T. KawaJcamil 

 August 1897). 



This species differs in respects from Potentilla tridentata Poland, and 

 P. amhigua Camb., though the leaflets of all three species are 3-dentate 

 at the apex, like those of Sibhaldia procumbens Linn. 



I have named it in honour of Dr. Kingo Miyabe, Professor of Sapporo 

 Agricultural College, and ray thanks are due to Mr. Takiya Kawakami, who 

 collected it and sent me kindly.
