There has been great diversity of opinion as regards this 

 Fern. Mr. Xewman figured it in the "Phytologist" as a distinct 

 species first as Lastrea uliginosa, and then as Lophodium uligino- 

 sum. Mr. Moore places it as the variety uliginosa of Lastrea 

 cristata; and in Hooker and Arnott's "British Flora" it is also 

 placed under this Fern, as Aspidium cristatum, var. uliginosum/ 

 and Mr. Braun calls it Aspidium spinulosum, var. uliginosum. 



This Fern and spinulosa seem to me to be distinct species.
