Rhizome short, scaly, the scales lanceolate-linear, black-brown, brown- 

 margined, rather entire. Stipes tufted, black-brown and pale-margined, 

 chaffy like the rachis, + 10 — 25 cm. long, the scales crowded, irregularly 

 radiate-flmbriate, partly persistent partly deciduous, brown or blackish. 

 Fronds lanceolate, 15 — 30 cm. long, 5 — 15 cm. broad, acuminate. Pinnae 

 approximate, subrhomboidal-oblong, blunt to acuminate, the edge broadly 

 crenate-serrate, the teeth inconspicuously crenulate, the base cuneate- 

 truncate, truncate or cordate, and sometimes subauriculate on the upper 

 side, cuneate or rotundate on the lower side; central pinnae the largest, 

 spreading, IV,, — 3 cm. broad near the base; lower pinnae not rarely 

 somewhat deflexed and subtruncate-rotundate on the lower side at the 

 base ; terminal pinna triangular, whether or not deeply incised at the base. 

 Texture coriaceous; surfaces copiously (not densely) scaly on both sides 

 on the costae and veins, the scales brown, capillary or palmato-fimbriate, 

 those of the upper side rather deciduous, those of the lower side rather 

 persistent; veins parallel, erecto-patent or the lower somewhat radiating, 

 distinct beneath, somewhat decurved. Sori linear, not reaching the margin 

 and costa; indusium firm, naked, persistent.
