Sikkim and Bhotan, 4,000-6,000 feet elevation ; Khasya, 

 3,000-5,000 feet. This is very near the Japan Lingua, but it appears 

 to differ sufficiently to be considered a species, besides the filamen- 

 tous hairs radiating round the scales, which it requires a magnifying 

 glass to detect, the habit is somewhat different and the scales of the 

 rhizome more free and copious. 



5. Niphobolus pannosus. {Mett) Rhizome wide-creeping, 

 slender, scales linear, dark coloured, closely adpressed ; stipes up to 



6 inches long, stellately scaly ; 

 fronds lanceolate up to 6 inches 

 long by i^ inch broad, nar- 

 rowed at both ends, coriaceous, 

 glabrous above, at least in age, 

 beneath densely matted with 

 stellate scales, the rays of which 

 are hair-like ; areoles in about 

 seven series between the costa 

 and margin, each including 2- 

 4 veinlets which are simple, 

 forked, free, or variously anas- 

 tomosing ; sori crowded, rather 

 small, 5-6 in a row between
