Rhizome thickly clothed with narrow, reddish-brown scales. Stipes ± 

 15 c.M. long, dark-t«H)Wn, with a few scales below like those of the rhizome, 

 naked above. Fronds deltoid, 7 — 25 c.M. long, nearly as broad; rachis naked. 

 Lower pinnae deltoid, pinnate, the higher ones simple, those at the apex 

 confluent. Pinnulae linear, crenato-lobate, the lobes extending V2"^3.y to the 

 costa, lowest pinnulae on the lower side much larger than the other ones. 

 Texture coriaceous; surfaces naked; veins ascending. Indusium intramarginal, 

 broader than deep.
