HISTORICAL SKETCH. 



The various regions of the world, from which members of the 

 Glossopteris flora have been recorded, are so scattered that it will 

 perhaps be most convenient, in a brief historical sketch of the rise 

 and progress of our knowledge of this flora, to consider each area 

 separately. 



I. Southern Asia. 



(«) India, 

 The first Indian specimens of Glossopteris, obtained from "Rana- 

 Gunge, near Rajeinahl," were described by Brongniart ' in 1828. 

 At the same time another important genus, afterwards known as 

 Schizoneura, was founded. 2 



Glossopteris Browniana, sp. no v. 

 Zeugophyllites — ? Schizoneura.* 

 Conral/arites = Schizoneura. 



In 1830 Brongniart, 4 in his " Histoirc des Vegetaux fossiles," 

 described and figured two Indian species of Glossopteris. 



Glossopteris Browniana, var. indica = G. indica, Schimper. 

 G. angustifolia, sp. nov. 



Boyle, 5 in the first part of his " Illustrations of the Botany of 

 the Himalayan Mountains," published in 1833, figured several 

 important types from the Bard wan Coalfield (Raniganj Group, 

 Damuda Series) of India. These specimens, now in the British 

 Museum, were re-examined by the present author in 190 1, 6 and 

 are also described in this volume. 



Trizygia speciosa, sp. nov. = Sphenophyllum speeiosum (Royle). 

 Vertebraria indica, sp. nov. 



Glossopteris danaoides, sp. nov. = Tceniopferis danceoides (Royle). 

 Pecopteris Lindleyana, sp. nov. = Cladophlebis Roylei, Arber.
