Information Rhizome shortly creeping with linear-lanceolate chestnut scales 3–5 mm long. Fronds closely spaced or appearing ± tufted, few to ± 10, 25–50 cm tall; stipe dark purplish brown, 7–25 cm long, appressed pubescent and with very narrow pale brown scales; lamina narrowly oblong to narrowly oblong-oblanceolate, 14–30 cm long, 3–9 cm wide, simply pinnate; pinnae coriaceous, 25–45 on each side of rhachis, linear to linear-oblong, 1.2–5 cm long, 1–6 mm wide, ± rounded at apex, cordate at the base, glabrous above, hairy on midrib beneath; rhachis with hairs and scales similar to the stipe; stalks blackish, articulated at apex, hairy; veins free, obscure. Sori and indusium continuous.

Information Rhizome c. 5 mm. in diam., short, creeping, with tufted fronds and with brown subentire narrowly lanceolate attenuate rhizome-scales up to 3 mm. long. Stipe atrocastaneous, up to 25 cm. long, terete, thinly pubescent with short appressed hairs and a few pale subulate scales, becoming glabrous with age. Frond erect, thinly coriaceous. Lamina up to 30 x 9 cm., very narrowly to narrowly oblong in outline, simply pinnate (the lowest pinnae undivided); pinnae petiolulate, up to 5 x 0.15 cm., very narrowly linear, obtuse, with a cordate base articulated at the apex of a short atrocastaneous petiolule; ventral surface glabrous, dorsal surface glabrous except for pale flexuous hairs along the costa; rhachis terete, atrocastaneous, persistently thinly villous with hairs and very narrow pale-brown scales. Sori in a continuous line at maturity; indusium continuous, erose, membranous.

Information Plants terrestrial or epilithic. Rhizome short-decumbent, to 30 mm long, to 5 mm in diameter, set with roots, closely spaced persistent stipe bases and scales, scales thinly crustaceous, ferrugineus, adnate, linear to subulate, irregularly and shallowly dentate, apex terminates in a small thin-walled cell or a short subulate cell, to 6 mm long, to 0.5 mm wide. Fronds crowded, erect, to 435 mm long, to 7 per plant; stipe rigid, atrocastaneus, terete, to 150 mm long, to 2 mm in diameter, initially densely scaled, scales chartaceus, stramineous to ferrugineus, sessile, filiform to subulate, entire, apex terminates in a small thin-walled cell or a short subulate cell, to 5 mm long, to 0.3 mm wide; lamina oblong-acute, 1-pinnate, to 300 mm long, to 90 mm wide, with up to 52 pinna pairs; rachis atrocastaneus, terete, initially closely set with hairs and scales similar to those on the stipe; pinnae petiolate, petiole to 2 mm long, closely set with hairs and scales similar to those on rachis, opposite to alternate, pectinate, generally more widely spaced basally, coriaceus, linear, entire, cordate to inaequilaterally cordate, acute, to 44 mm long, to 3 mm wide, glabrous adaxially, abaxially with filiform scales and pluricellular, uniseriate hairs along costa, to 2 mm long, articulated; costa adaxially sulcate. Venation obscure, forked, free, branches terminate near the margin. Sori forms a continuous line along a marginal vascular commissure; receptacle with simple, pluricellular, uniseriate hairs terminating in an orange oblong to clavate cell, to 0.5 mm long; sporangium long-stalked, stalk simple, 3-seriate below capsule, capsule globose to obovate in lateral view, with (14-)14(-16) indurated annulus cells, epistomium (4-)4(-6)-celled, hypostomium (4-)4(-6)-celled, stomium with 4 narrow cells with conspicuously thickened walls; indusium continuous, near-marginal, chartaceus, entire, to 0.4 mm wide. Spores 32 per sporangium, brown, smooth-granulose, monolete, elliptic, (66-)68(-72) x (44-)45.33(-48) (m, or tetrahedral-globose, trilete, (50-)54(-64) (m. Figure 19E & F.

Information Rhizome very shortly creeping, with very narrowly lanceolate somewhat curved scales 3–4 mm long, either with dark centre and paler margins or entirely pale, ± longitudinally ribbed; roots with dark shiny setiform hairs. Fronds 3 remaining but probably up to 7, tufted, 13–16 cm tall; stipes relatively broad, ± 2.5 mm in diameter, dark brown, covered with dense mostly appressed upwardly directed brown hairs; rhachis similar; lamina pale green, oblong, 4–7 cm long, 4.5–6 cm wide, simply pinnate; pinnae in 8–10 pairs, oblong-lanceolate, 1.8–3.5 cm long, 4–7.5 mm wide, separated from each other by 2–5(–8) mm, narrowed to a subacute or ± rounded apex, distinctly cordate at base, with pale hairs having brown joints scattered on the under surface and also a few above on the midrib; basal part of midrib dark beneath for 5–6 mm and stalklets 1–2 mm long, both hairy like the rhachis; venation entirely free but not visible without strong transmitted light. Sori in marginal line and with a continuous pale membranous reflexed indusium.
