///It is well known that southwestern China including western Guizhou Province and eastern Yunnan Province has been relatively an ideal place for the research of the Permian-Triassic floral transition because the Permian-Triassic terrestrial deposits there are continuous and fossiliferous. Recent investigation on the biostratigraphy of the Mojiang region in Yunnan yielded abundant plant fossils from the Late Permian Changhsingian Yangbazhai Formation. This latest Permian flora includes 19 species of 14 genera. The dominant plant taxa are all typical elements of the well-known Cathaysian flora. As a consequence, this flora indicates that the latest Permian flora in this region are certainly of the Cathaysian type.
