Obs. — It is difficult to reconcile the humble G. reftans 

 and its allies as belonging to the same genus with the 

 splendid G. Sandviceitse and G. costata, the first being a 

 native of the Sandwich Islands, having an erect arborescent 

 cordex, 1^ feet high, bearing a crown of long stipate fronds 

 6 feet in length, which, with G. costata of India and G. 

 pennigera of New Zealand, which also has an arborescent 

 caudex, seems to have some claim to rank as a distinct 

 genus. 



In Beddome's " Ferns of British India," G. costata and 

 G. lineata are said to be indusiate, and consequently belong 

 to Nephrodium.
