New Records for the Liverwort and Hornwort Flora of Vietnam, 3

Abstract

Pierre Tixier deposited a large amount of bryophyte collections, including epiphylls, in the Cryptogamic Herbarium of the Natural History Museum in Paris (PC). A very large part of his valuable epiphyllous specimens collected between 1957 and 1965 in the southern half of Vietnam remained unidentified. Based on study of a small portion of these collections, 44 species are reported including six new to the country (Dendroceros subplanus, Ceratolejeunea singapurensis, Cheilolejeunea rigidula, Cololejeunea angulata, C. stephanii and Thysananthus aculeatus). Ceratolejeunea and Dendroceros are genera new to Vietnam.
