The Yangtze valley in this paper roughly includes the areas of eastern Sichuan, western
Hubei, northwestern Hunan, eastern Hubei, northern Jiangxi, southern Anhui and southern
Jiangsu Provinces. In recent some years, a Lycopsid flora, represented by Pleuromeia and An
nalepis, has been found from the Middle Triassic Series in this valley. Generally speaking, the
Middle Triassic floras are quite rare at home and abroad. This discovery of the flora, therefore
will be of important significances for supplying a gap of Triassic plant assemblages in South Ch
na,the phytogeographical regionalization and the correlation of the Middle Triassic floras in all
the world
