1XX HISTORICAL SKETCH. 



•which are in the Berlin Museum, and identified Gangamopteris 

 cgclopteroides, var. attenuate/,. As he was the first to point 

 out, there is a remarkable association in Brazil of such typical 

 members of the Glossopteris flora as Gangamopteris cgclopteroides 

 and Neuropteridium validum, with a common Upper Carboniferous 

 plant of the Northern Hemisphere, Lepidophloios laricinus. 



In a further paper Zeiller 1 gave a fuller account of these 

 specimens, with additional determinations of leaves of a Lepido- 

 dendron or Sigillaria, various spores of Vascular Cryptogams, and 

 pollen-grains. A new species of Cordaitean stem, from the valley 

 of the Jaguarao, is described and figured as Dadoxylm Pedroi, 

 sp. nov. 



So far as I am aware, Glossopteris itself as yet has not been 

 discovered, beyond doubt, in Brazil, though it has been obtained 

 from the Argentine Republic. 



(b) Argentine Republic. 



The earlier descriptions of plant-remains from Argentina relate 

 to fossils which are of Rhaetic age. 2 In 1891, Lower Carboniferous 

 plants were described by Szajnocha. 3 



In 1894, Professor Kurtz 1 described members of the Glossopteris 

 flora from the Argentine Republic. Tbe specimens were obtained 

 from Bajo de Velis. Kurtz compared tbis flora with tbat of 

 India and South Africa.
