Rhizome suberect, densely clothed with very long, yellow-brown, thin, 

 lanceolate, entire scales. Stipes 25 — 35 c.M. long, the lower half scaly like 

 the rhizome, the upper half like the rachis. Fronds linear-lanceolate, 35 — 100 

 c.M. long, 15 — 30 c.M. broad. Pinnae sessile, linear, 1% — 2'/2 c.M. broad, 

 the apex acuminate, toothed, Ihe edge cut down nearly to the costa; lower 

 pinnae shorter, but not reduced. Lobes linear-oblong, close, blunt, toothed 

 at the apex, 3'/! — 5 m.M. broad, the edge entire or slightly crenate. Tex- 

 ture coriaceous; rachis scaly; veins forked, bearing the sori at the base of 

 the anterior branches, in 1 row on each side of the costulae.

Rhizome short, erect. Stipes tufted, slender, 15 — 50 c.M. long, dark- 

 coloured, polished, scaly at the base. Fronds 30 — 60 c.M. long, 15 — 30 c.M. 

 broad, oblong-lanceolate. Pinnae + 8 — 10 on each side below the pinnatifid 

 apex, + 5 — 4 c.M. broad, the base subtruncate, the apex short-acuminate, 

 the edge cut down nearly to the midrib into linear-oblong, crenate or entire 

 lobes; the lowest ones deflexed, rather shorter than the others with some of 

 the lobes on the lower side sometinaes prolonged. Texture papyraceo-herba-
