Rhizome short-decumbent, up to 2 mm in diam., set with roots, short, closely spaced, persistent stipe bases and scales; scales ferruginous to castaneous, sessile, subulate, cuneate to cordate, dentate, up to 8 x 1 mm. Fronds crowded, pendent, up to 720 mm long. Stipe poorly differentiated, up to 4 mm long, initially sparsely set with scales similar to, but smaller than, those on rhizome. Lamina carnose-coriaceous, simple, linear, entire, up to 716 x 3 mm, glabrous adaxially and abaxially; venation obscure. Sori along a near-marginal vascular commissure, sunken in 2 submarginal grooves extending entire length of lamina; receptacle paraphysate.
Rhizome shortly creeping, c. 3 mm in diameter, set with narrowly lanceolate, attenuate, clathrate, strongly pseudo-serrate, dark brown rhizome-scales up to 10 mm long. Fronds tufted, simple, sessile, carnose-coriaceous, pendant; lamina very narrowly linear, with a pale brown or pale greyish green base when dried; midrib and veins obscure. Sori in two deep intramarginal grooves and with intestiniform paraphyses.
Rhizome shortly creeping, set with dark brown rhizome scales up to 10 mm long. Fronds sessile, very narrowly linear to narrowly elliptic, suberect to pendulous, glabrous. Sori exindusiate, in 2 marginal, submarginal or intramarginal grooves, midrib and veins obscure.
