DisTEiB. Tlie type is rather of the alpine character, being 

 found in liigh mountains of Asia such as the Himalayas, and those 

 of Borneo and west central China. 



In my former paper above cited, 1 referred tliis Formosau 

 species to Potentilla leucouofa Don. After studying more carefully, 

 I found that there is a little difference between this and that. 

 It is not, however, without hesitation, that I have described it as 

 a new variety. The present plant differs from tlie type mainly 

 in the absence of whorled leaves at the base of an umbel.
