Abstract: This paper deals with fifteen plants, all new to science, of late Triassic (Keuper), found in the district Yungjen, Yunnan. These plants are Angiopteris antiqua, A. yungjenensis, Pecopteris callipteroides, Rireticopteris microphylla, Lureticopteris mega- phylla, Mixopteris intercalaris, Pachypteris chinensis, P. yungjenensis, Sagenopteris glossopteroides, S. stenofolia, Sphenozamites yungjenensis, Otozamites megaphyllus, O. recurvus, Sphenobaiera bifurcata and Yungjenophyllum grandifolium. The genera Rireticopteris, Lureticopteris, Mixopteris and Yungjenophyllum all are recommended as new species. The fossil Originally described as Lonchopteris (?) sp. from the Lower Chinle Formation of Arizona by Daugherty (1941) is suggested better to be included in the new genus Rireticopteris, as R. arizonica. The fossils formerly described as "Glossopteris indica Schimper" and "G. angus- tifolia Brongn." by Zeiller (1902-3) from the Upper Triassic of Tai-Pin-Tchang (Yunnan) are included in Sagenopteris glossopteroides and S. stenofolia respectively.
