I have not seen the type of Eurhynchium savatieri but have compared the types of Rhynchostegium patentifolium with so-named Japanese specimens in h and H-BR, as well as the figures and the description of Eurhynchium polystictum given by Takaki (1956). They fit well to each other. The plants are flat, the leaves are ovate and without decurrent bases. This character separates E. savatieri from most of its relatives. The plants also are somewhat glossy. A third specimen cited under the name E. patentifolium by Levier (1906) "in monte Tui-kio-san, 19 Oct 1896, J. Giraldi," (H-BR) represents another taxon which seems to be distinct.
