Nomenclatural history of the generic name Haplocladium (Bryophyta: Leskeaceae)

摘要

The nomenclatural history of the moss generic name Haplocladium is discussed. Originally, this name was validly published in 1879 by Karl Muller of Halle as a subsection, Hypnum subsect. Haplocladium. It gained generic status in 1897 when the same author provided a brief diagnosis of the new genus Haplocladium. Under Art. 41.4 Haplocladium is treated as a name at a new rank published without reference to the presumably intended basionym Hypnum subsect. Haplocladium. It is shown that the authorship of Haplocladium microphyllum, which was previously attributed to "(Hedw.)Broth.", should correctly be ascribed to "(Hedw.) Mull.Hal." (in Hedwigia 36: 140. Jun 1897). The confusion associated with H. gracile is clarified and the authorship of this name is correctly attributed to "(Schimp.) Mull. Hal." (in Hedwigia 36: 140. Jun 1897).
