What is 'Hypnum aduncoides' (Musci, Hypnaceae) from Africa?

摘要

Hypnum aduncoides (Brid ) C. Mull.', raised in rank from H cupressiforme Hedw. var aduncoides Brid , is an incorrect name erroneously based on a specimen with a different circumscription from the type. The moss named 'H. aduncoides', which has been recorded from East and South Africa, Madagascar and Mascarenes, belongs to Hypnum, sect Curvifolia and is referable to H. macrogynum Besch., known from the Himalayas, southern China, etc. Taxonomy and distribution of H. macrogynum and three other related species of sect Curvifolia are discussed.
