Rhizome short-ascending, sparingly scaly; scales lanceolate-subulate, 

 pale-brown, entire. Stipes ± 30 cm. long, pale-brown, scaly, the lower scales 

 rather approximate, similar to those of the rhizome, the higher scattered, 

 smaller, becoming similar to those of the rachises. Fronds ovate, + 30 

 cm. long and half as broad, acuminate, 3-pinnate in the lower part, the 

 rachises above sparingly velutinous, giabrescent, provided with a few 

 deciduous, scattered, subfiliform, pale-brown scales. Pinnae spreading, 

 subhorizontal, close, stalked, acuminate, obliquely truncate at the base, 

 often slightly upcurved, the largest + H'/j cm. long, 3 cm. broad at the 

 base. Pinnulae approximate, short-stalked, blunt, mostly pinnate in the 

 lower part and pinnatifid towards the apex, of the lowest pinnae the 

 central posterior the largest, to 2 cm. long, of the following pinnae the 

 lowest anterior the largest, to P/^ cm. long. Segments oblique, oblong, 

 sharply toothed, the lower free, the lowest anterior often more spreading, 

 short-stalked, oblong, to 5 mm. long, blunt, deeply lobed, cuneate at the 

 base, the lobules acute or acutely 2 — 3-dentate at the apex. Texture 

 firm-herbaceous; surfaces naked; rachises provided above with erect- 

 adpressed, spine-like appendages at the base of the petioluli; costae 

 spinulose above; veins beneath naked or sparingly and minutely fibrillose.
