As a new variety of this species Air. Shunzo Komatsu described a 



plant from Nikko in Matsumura's Icones Plantarum under the name 



var. niko-montanum. But that is a very remarkable plant and readily 



distinguishable from this by having not rugose leaves and deciduous 



perulse. I saw it myself on the peak Nyoho, and it looks to me rather 



much more resembles to R. brachycarpum. Dr. Gen-i-chi Koidzumi 



labelled to a specimen of same plant which he collected on m't Ontake 



giving a new name of R. brachycarpum var. lutcscens. Still that is 



different widely from R. brachycarpum of its leaves glabrous and of 



yellowish flowers. It should be named as R. niko-montanum, Nakai
