Stipes slender, to 15 c.M. long or longer, the inner side deeply sulcate, 

 the groove tomentose, the rest naked; rachis slightly hirsute. Fronds deltoid- 

 lanceolate, long-acuminate, to 27 c.M. long, 16 c.M. broad at the base, pin- 

 nate. Pinnae to 20-jugate, subcontiguous, spreading, falcate; lowest pinnae 

 largest, to 8 c.M. long, Vj^ c.M. broad, ovate-elongate, short-acuminate, pinna- 

 tifid nearly to the costa, the segments linear, moderately acute, suberect, 

 somewhat falcate, the lowest very abbreviate, the central the largest, + 1 '/4 c.M. 

 long, 4 m.M. broad, the highest rather suddenly diminished into the denticu-

 loped plants, but similar to the central pinnae in the fronds of the younger 

 plants ; central pinnae short-slalked, subfalcate, + equally truncate at the base 

 on both sides, auricled on the upper side, linear-lanceolate, short-acuminate, 

 pinnatifid ± Va'^^Y down to the costa, the segments linear-lanceolate, falcate,
