Characteristics

Rhizome short, creeping, up to 7 mm diam., densely set with dark brown sclerified, narrow-lanceolate to cordate, entire or shallowly crenate scales, often with few filiform filamentous outgrowths near base, up to 3 x 0.5 mm; stipe caespitose, firm, pale brown shallowly sulcate ventrally, trophophyll stipe up to 170 mm long, sporophyll stipe usually longer than that of trophophyll, up to 235 mm long; sclerified, narrow-lanceolate entire scales with inrolled margins frequent along the stipe of the trophophyll, up to 4 x 0.3mm; trophophyll simple, entire to shallowly undulate, herbaceous, broad to narrow-lanceolate or linear-acuminate, base cuneate to obtuse, up to 210 x50 mm, venation free, often reticulate, ventral surface with sclerified, entire, narrow-lanceolate and minute stellate scales, up to 0.1 mm diam., narrow-lanceolate scales more commonly confined to midrib of ventral and dorsal surfaces, continuous along margin, stellate scales absent on dorsal surface; sporophyll simple, entire, herbaceous, lanceolate, base obtuse to acute, up to 100 x 20 mm, venation reticulate, ventral and dorsal surfaces with few narrow-lanceolate, entire, sclerified scales along midrib; sori acrostichoid except for membranous margin, annulus cells small, 12-celled.
More
Rhizome up to 4 mm in diameter, set with dark brown, lanceolate, attenuate, entire rhizome-scales up to 6 x 1 mm. Fronds clustered, arching, firmly herbaceous; stipe stramineous to pale brown, fairly densely set with scales, becoming subglabrous with age; sterile lamina very narrowly oblong to very narrowly elliptic (or narrowly elliptic in small fronds), acuminate, set mainly along margin and midrib with dark brown scales c. 1.5 mm long (smaller along margin) and with substellate scales on lamina surface, base narrowly to broadly cuneate, abruptly decrescent or not; midrib shallowly sulcate above, convex below; fertile lamina narrowly oblong, acute, up to 125 x 30 mm, narrowly ovate in small fronds, base broadly cuneate, hardly decurrent.
Rhizome short, decumbent to erect, up to 6 mm in diam., scaled. Fronds erect to arching, up to 250 mm long. Stipe variously scaled. Lamina simple, herbaceous, sterile broad to narrow-lanceolate or linear-acuminate, up to 210 x 5 mm, abaxially with dark brown subulate scales along the midrib and margins.
Rhizome up to 4 mm in diameter, set with dark brown rhizome scales. Sterile lamina set with scales longer than 1.5 mm, only stellate scales present, narrowly oblong to very narrowly elliptic, acute, base shortly decurrent.
