Abstract
A revision of the liverwort genus Pleurozia in Thailand leads to the recognition of three species including P. acinosa (Mitt.) Trevis., P. gigantea (F.Weber) Lindb. and P. subinflata (Austin) Austin. Each species is described and illustrated, with details on ecology and distribution as well as a key to the species. In addition, an appendage on the keel of the dorsal lobule is described in P. gigantea and P. subinflata.
