inhabits sparsely wooded grassland at the fringe of a swamp in the
mountain, the stem standing 0.6 to 1.2m with the leaf at the stem's
tip, pedately divided into leaflets. The appendage at the end of
inflorescence curves in an S letter in the lower part and then goes
straight up, which characterizes this species. Ministry of the
Environment designates this species as a VU, and in most
prefectures, RDB lists as a CR+EN.
