A comparison between the Upper Triassic floras of China and the Rhaeto-Liassic floras of Europe and East Greenland

A survey is given of the geological and geographical distribution of the Upper Triassic floras of China, based chiefly on many articles published in Chinese during the last ten years. This is followed by a comparison between the Upper Triassic flora of China and the Rhaeto-Liassic floras of Europe (Sweden, Germany) and East Greenland. It is pointed out that important floral assemblages (for example that of the Liassic Thaumatopteris schenkii Assemblage-zone) occur considerably earlier in China (especially in S.W. China) than in Europe and East Greenland.
