On the basis of work by J. Kudo (in Bull. Natl. Sci. Mus., Tokyo, Ser. B. 13: 69-80. 1987) it is clear that the Taiwan plants, although closely related to the more southern Japanese species of the H. pseudopetiolatum group. Viz. H. kiusianum Koidz., differ from it interalia in capsule shape and habit. They should therefore be treated as a separate species, H. taihezanense.
