BAKER'S description is as follows : " Stipes 2 ft. or more long ; tetrago- 

 nous, glossy, stramineous, naked; fronds 3-4 ft. long, 1-2 ft. broad; lower pinnae 

 sometimes 1 ft. long, 1 J in. broad, cut down nearly to the rhacliis into close 

 acute or bluntish entire lobes 2 lin. broad ; texture rigid, subcoriaceous ; rhacliis 

 on both sides naked ; veinlets simple, often 20 on a side ; the sori close to 

 the raised midrib." The description here quoted agrees very well with our 

 plant, except the ciliolate margins which however are mentioned in BEED. Fern.
