Diplothmema Loshii. 



Stur, Culm Flora, heft 2, p. 230. 



Remarks. This specimen, though nearly allied to Mariopteris acuta, 

 Brongniart, sp., possesses more generally the characters of N. Loshii, Brongt., 

 sp. It is quite possible that eventually Mariopteris (Sphenopteris) acuta, 

 Brongt, sp., and M. Loshii, Brongt., sp., may both prove to be only varietal 

 forms of M. latifolia, Brongt., sp.
