Kunze, in his "Index Filicum," collects most of the ahove 

 under the head Aspidium, preferring to give them in sections; 

 he only recognises Nephrodium, Lastrea, Polystichum, Bathmium, 

 and Sagenia as groups in Aspidium, whilst CyclopeUis, Fadyenia, 

 Nephrolepis, Oleandra, Cystopteris, Didymochlcena, etc., he sepa- 

 rates from Aspidium, yet his Catalogue of the tribe Aspidium 

 numbers above one hundred species. 



Moore and Houlston, in their "Genera and Species of Culti- 

 vated Ferns," divide Aspidiece as follows: —
