The present species is closely related to Tofieldia nutans Willd., from which, 

 however, it is readily distinguished by its blackish capsules, looser inflorescence, 

 and somewhat thicker green perianth-segments, which are tinged with a blackish 

 purple or sometimes ochraceous color, and which are provided generally with three 

 nerves. The stem is, moreover, firmer and strict ; and the styles are shorter and 

 thicker and are tipped with a small and not prominent stigma. Abundant 

 materials of the present species were collected on the summit of Mt. Yubari and 

 adjacent peaks during 1912 and 1913 by Messrs. Nishida, Yanagisawa and 

 Hamana. We have delineated the specific cliaracter of this species from more 

 than 30 specimens. It is of extreme interest to find this rare plant also on Mt. 

 Shirouma in the Province Shinano. 



Forma rishiriensis has been included thus far in Tofieldia nutans Willd., — 

 and not without reason ; for at first sight it looks like a depauperated form of 

 that species. Fortunately Me have at hand a large number of the specimens of 

 this plant enabling us to pass better judgment on its affinity. The plant has in 

 common with Tofieldia fusca many important characters in the capsule, style, 

 stigma and perianth -segment.
