Rhizome wide-creeping, sparcely scaly; scales rufo-brown, ovate-lanceolate, acu- 
minate, thin, clathrate; frond distant, 40-60 cm long, 5-7 cm broad, broadly lanceolate, 
acuminate, entire, gradually narrowed and long-decurrent down ton ear the base of 
sparcely scaly stipe; texture herbaceous, brownish-green upon drying; venation distinct, 
lateral main veins subpatent, parallel, flexuose, about 8 mm apart, the intervening veinlets 
anastomosing in 3-rowed rectangular areole with divaricate included veinlets; sori large, 
oblong, short linear or roundish, one-rowed between each pair of lateral veins, exindusiate.
