The most magnificent Hymenophyllum known, growing in 

 shady woods, on trunks of trees in Chili and Juan Fernandez. 



The fronds, which are broad, rigid, erect, smooth, and 

 shining, are tripinnatifid ; segments broadly linear-obtuse, rounded, 

 and bifid, ultimate ones attenuated. 



Rachis broadly winged. Stipes stout, rigid, and pale in 

 colour. 



Length of frond from eighteen to thirty inches; and eight 

 inches or more broad. Colour bluish green or glaucous. 



Involucres supra-axillary, marginal, minute, ovate, two-valved 

 to the base, and free; valves entire. Receptacles exserted. 



Requires a very humid airy atmosphere, with a temperature 

 from 40° to 65°. 



My thanks are due to Mr. Backhouse, of York, for the 

 frond illustrated.
