Engler and Prantl, also Christ, constitute the section Dijolazium 

 of AspJenium as a separate genus. As Asple?ikim, Mueller (Game's 

 list) records it from Norfolk Island.

Christ, also Engler and Prantl, separate Athyrium from 

 Asplenmm. A. Cunningham in He ward has the note "Asplenium 

 assimile, Endl., Prod. p. 10, is AUantodia australis, R.Br." But 

 according to Synops. Filic. p. 229, AUantodia, R.Br., is synony- 

 mous with Asplenium u7nbrosum, J. Sm., and not with its var. 

 assimile.

 Linn.: Nephrodium parasiticura (Linn.), Baker: Nephrodium

Christ and Diels agree thd^^t par asiticum should be the specific 

 name, though they differ about the genus. Diels separates 

 Nephroiium from Aspidium as a genus. Christ concurs with 

 Bentham and Mueller in leaving Nephrodium with Aspidium. 



The plant is recorded from the Island as A. molle, Sw., by 

 Mueller in Journ. Bot. xxii. 290. 



''Nephrodium remotum, Hew. (nov.sp.) frondibus pubescentibus lanceo- 

 latis pinnatis, pinnis lineari-lanceolatis sessilibus oblique crenatis ciliatis

 Indusium reniforme pilosum. Shaded woods. This fern belongs to a section 

 of Nephrodium extremely difficult to determine specifically, but the character
