The literatures on the Permian Sporae dispersae are rather meagre and scattered ascompared with those on the Carboniferous.The correlation of sediments of long geo-graphical distance in this period is thus nearly impossible at this moment.As far as isknown to the present writer,the contributors to the Permian microflora are Dalhunty(1945,49),Balme(1952,1955,1956),Imgrund(1952,1960),Klause(1953),Potonie& Klause(1954),Leschik(1956);Luber(1938),Kara-Murza(1952),Samoilovich(1953),Zoricbeva & Sedova(1954),Andreeva(1956),Zauer(1960),Medvedeva(1960)andothers.
