Nomenclatural Notes on Pterogonium (Bryophyta, Leucodontaceae)

Abstract

Abstract A taxonomic and nomenclatural history of the moss genus Pterogonium Sw. is outlined and the illegitimacy of this name is confirmed. Nogopterium Crosby & W. R. Buck, the name of a new genus erected to replace the illegitimate Pterogonium, is accepted as validly published. This genus consists of five species, two of which, N. coreense (Cardot) Tad. Suzuki and N. tenellum (Tad. Suzuki & Z. Iwats.) Tad. Suzuki, have only recently been transferred to this genus. The transfer of the fifth species, N. tsilingense (P. C. Chen) Tad. Suzuki ex Ochyra & Bedn.-Ochyra, comb. nov., is effected in the present account.
