Frond usually large, broadly obovate. Apex obtuse or emar- 

 ginate. Midrib stout, especially in the lower portion of the 

 frond, but not persisting quite to the apex. Lateral nerves 

 arched at midrib, forming one or two series of comparatively 

 broad and short meshes, and then subdividing into a number 

 of close, almost parallel veins, often very oblique, forming 

 extremely narrow, elongate meshes. 



The characters which especially distinguish this species are 

 the breadth of the fronds, the stoutness of the midrib, and the 

 contrast between the fine, close, and pseudo-parallel nervation of 

 the greater portion of the lamina, and the nervation bordering 

 on the midrib. 



It seems clear from a re- examination of these broad -leaved 

 Glossopterids that G. damudica, Feist., must be united with Dana's 

 G. ampla. Although Feistmantel's name is the best known, Dana's, 

 as being the older, should have priority. The only difference 

 which I can find between these fronds is that the nervation in the 

 Indian leaves (G. damudica) is rather more acute than in the 

 Australian specimens, where the obliquity is very marked in 

 the greater portion of the frond. I am unable, however, to attach 

 any weight to this character. I have had an opportunity of 

 comparing the fine specimens of the Australian fronds in the 

 Clarke Collection of the Sedgwick Museum, Cambridge, with the
