New records for the liverwort and hornwort flora of Vietnam 2. Bazzania Gray and some other collections of Pierre Tixier in the National Museum of Natural History, France.

As a large part of the bryophyte collection of the late Pierre Tixier (1918-1997), deposited in the Cryptogamic Herbarium of the Muséum national d'Histoire naturelle, Paris (PC), was unidentified, the Author has started to study the rich collection of Bazzania Gray species as well as some other taxa. They were not identified by Tixier, because during his lifetime the genus had not been revised yet. Long ago, the Author himself recorded nine species from northern Vietnam, and a couple of studies were published on Vietnam and neighbouring areas. Today, by identifying Tixier's collection, the number of Bazzania species known in Vietnam has been increased to 28. [ABSTRACT FROM AUTHOR]
