Rhizome erect or suberect, densely clothed with brown, narrow, lanceo- 

 late scales. Stipes to 18 c.M. long, slightly scaly at the base. Fronds del-

 each side, pinnate, the lower ones stalked, lanceolate, acuminate, to 4 c.M. 

 broad. Pinnulae to 1 c.M. broad, lanceolate, bluutish, the upper base broadly, 

 the lower narrowly cuneate, the edge cut down '/^ — '/s-way to the costa 

 into linear-oblong, nearly close lobes. Lobes erecto-patent, rounded and cre- 

 nate to toothed at the apex. Texture herbaceous to subcoriaceous; rachis 

 pale-coloured like the stipe; main veins pinnate in the lobes; veins few,
