Rhizome thick, creeping. Stipes erect, firm, + 60 c.M. long and like 

 the main rachis castaneous, slightly puberulous, rather glabrescent. Fronds 

 100 — 120 c.M. long, + 50 c.M. broad, 4-pinnatifid. Largest pinnae ± 30 

 c.M. long, + 11 c.M. broad, acuminate, with the rachis puberulous below; 

 lower pinnae reduced. Pinnulae lanceolate-deltoid, distinctly acuminate. Ter- 

 tiary segments lanceolate-deltoid, obtuse, decurrent, subpetiolate, the lowest 

 acroscopical ones the largest, to 2 c.M. long, + 1 c.M. broad, cut down on 

 each side to a winged costa into + 4 subremote, obtuse or truncate, entire or 

 obscurely serrate lobes. Texture herbaceous; surfaces naked, the lower paler
