Fronds erect. Stipes rather short ; scales very numerous, firm, at 

 first brown, ultimately dark fulvous or maroon, generally with 

 a maroon-coloured spot or stripe at the base, ciliate, the lowest ones 

 broadly lanceolate, the upper ones linear, intermixed with very 

 numerous firm hair or bristle-like ones, almost all persistent so that 

 the rachis is permanently scaly. Lamina subcoriaceous, yellowish- 

 green tinged with olive, with bright fulvous scales when it is un- 

 folding, ultimately dark green, conspicuously paler and sometimes 

 subglaucous beneath, where it is not glandular even on the rachis, 

 oblong or narrowly elliptical-oblong, pinnate ; lowest pinnae very 

 slightly broader than the others, and as well as those in the middle 

 of the stem spreading at right angles to the racbis or slightly 

 pointing towards the apex of the frond, pinnate, all of them flat or 

 slightly concave ; pinnules contiguous, strapshaped or oblong- 

 strapshaped, attached by a base which is commonly broader than the 

 rest of the pinnule, or in very luxuriant specimens narrower than the 

 lower part of the pinnule, not tapering to the very obtuse apex, faintly 

 crenate-serrate, or rarely inciso-serrate, flat or with the apices slightly 

 bent inwards. Indusium small, very convex, with the margins incurved 

 over the sporangia, glabrous. Spores with a few rather large blunt 

 separate tubercles.

Fronds inclining backwards. Stipes very short ; scales numerous, 

 rather thin, pale ferruginous concolorous, fimbriate-ciliate, studded 

 with a few minute glands, the lower ones lanceolate, the upper ones 

 linear, intermingled with rather numerous flexuous hair-like ones, 

 most of them subpersistent so that the rachis is permanently more or 

 less scaly. Lamina subcoriaceous, bright green with very pale 

 scales when it is unfolding, afterwards dark green, only slightly 

 paler beneath, where it is minutely glandular elliptical or oblong- 

 elliptical, pinnate ; lowest pinnae a little broader and more triangular
