CONIOPIERIS. 99 



Brongniart's genus to some of the species originally placed in his 

 •group Sphenopteris- Bicksonioides, including the Yorkshire species, 

 C. Mwrayana and Tympanophora racemosa. For reasons stated 

 l)elow, I regard most of the specimens previously identified as 

 Sphenopteris, Pecopteris, Thyrsopteris, or Coniopteris Mwtrayana 

 as identical with Sphenopteris hymenophyUoides, Brongn., and the 

 latter specific name has therefore heen adopted.
