2. DISTRIBUTION IX SPACE. 



The Glossopteris flora flourished in Peraio-Carboniferous times 

 in four great provinces of Gondwanaland, viz., India, Australasia, 

 Southern Africa, and South America, and in certain regions outside 

 these countries. In the succeeding Triasso-Rhaetic period some 

 members of the flora still survived, and these had an even wider 

 distribution. 



Europe : Russia. — The Glossopteris flora is found in the Permian 

 beds of Soukbona and Petite Dwina. 1 The genus Phyllotheca is 

 also recorded from Northern Russia.' Survivals of this flora are 

 found in the Triasso - Rhsetic rocks of Germany, Sweden, and 

 elsewhere. 



Asia : India. — The most important Glossopteris-bearing rocks in 

 Asia are the Lower Gondwanas of India, of which the following are 

 the chief divisions : — 3

Members of the Glossopteris flora have also been recognised in 

 Kashmir 4 (Permo-Carboniferous), Afghanistan and Persia 5 (Permo- 

 Carboniferous), Asia Minor 6 (Upper Carboniferous), and the Altai 

 and Siberia 7 (Permian). Survivals of the Glossopteris flora also 

 occur in the Triasso-Rhaetic rocks of India (Panchet division), 

 Tonquin, 8 and China. 9
