Stipes ± 35 c.M. long, stramineous, muricate. Fronds to 80 c.M. long, 

 ovate-lanceolate, with several to numerous spreading pinnae. Lower pinnae 

 10 c.M. apart, upper 4 c.M. apart, all petiolate, on stalks to 1 c.M. long

 suddenly narrowed or rounded on both sides. Texture thin-herbaceous; rachis 

 naked, smooth or muricate; main veins fine, pinnate in the lobes with the 

 short sori on the branches.
