Stipes tufted, + 1^1^ — 10 cm. long, deciduously hairy and at length 

 apparently copiously glanduloso-punctulate, as is the rachis, the lower 

 part scaly, the hairs spreading, fine, relatively long, the scales spreading, 

 lanceolate, brown, slightly crisped, entire, with the cells rather thick- 

 walled. Fronds lanceolate, + 10 — 15 cm. long, + 6 cm. broad, acuminate. 

 Pinnae ± 10 on each side below the terminal one; terminal pinna 

 triangular-elongate, subcrenate towards the blunt apex, gradually deeply 

 pinnatifld into linear, blunt, horizontal, entire, crenated or repando-lobate 

 lobes towards the subtruncate base; lateral pinnae horizontal, remote; 

 higher pinnae adnate, not rarely connected with the terminal one, lobed 

 below the moderately long, linear-oblong, entire or subentire, blunt apex; 

 central pinnae similar but gradually deeply incised towards the subtruncate 

 base, the base + ■''.4 — 1 cm. broad, the segments linear-oblong, entire or 

 repando-crenate, + l'/2 — 2 mm. broad; lowest pinnae the largest, + 4 

 cm. long, 1 — 1 ',4 cm. broad at the middle, deflexed, subpetiolulate, with 

 the lower posterior segments gradually abbreviated, the lowest anterior 

 segment free, oblong, blunt, lobed, narrowed at the base. Texture firm- 

 herbaceous; surfaces deciduously hairy, the costae at length more or less 

 punctulate; costulae pinnate in the lobes; veins simple, to 6 on each
