Plants epilithic or epiphytic. Rhizome erect to suberect, to 15 mm long, to 2 mm in diameter, set with roots, crowded persistent stipe bases and scales, scales chartaceus, castaneus to ferrugineous, clathrate, sessile, lanceolate, cordate-imbricate, margins basally with a few scattered filiform outgrowths terminating in an enlarged obovate gland-like cell, entire towards the apex, apex terminates in an oblong thin-walled cell, to 5 mm long, to 1.2 mm wide. Fronds crowded, to 9 per plant, caespitose, arching, to 300 mm long; stipe firm, green, basally sulcate, centrally raised apically, to 80 mm long, to 1 mm in diameter, sparsely scaled, scales chartaceus, castaneus to ferrugineous, clathrate, sessile, lanceolate to subulate, cordate to cordate-imbricate, with scattered filiform outgrowths terminating in an enlarged obovate gland-like cell along the margin, apex terminates in an oblong thin-walled cell, to 3 mm long, to 0.3 mm wide; lamina anadromous, 1-pinnate, linear-cuneate, to 230 mm long, to 27 mm wide, with up to 24 pinna pairs, proliferous, bud borne at the apex of a rachis extension; rachis green, firm, sulcate, centrally ridged, sparsely scaled, scales similar to, but smaller than, those on the stipe; pinnae petiolate, petiole to 1.5 mm long, opposite to alternate, basally widely spaced, pinnae in the lower third of the lamina gradually reduced, coriaceus, rhombic-dimidiate to cuneate, lobed, in the larger pinnae the proximal acroscopic lobe shallowly 2 to 3-lobed, to 13 mm long, to 9 mm wide, glabrous adaxially and abaxially; costa adaxially slightly raised. Venation anadromous, adaxially obscure, evident abaxially, ending in the teeth near the margin. Sori linear, lunate, medial on the simple vein branches, to 3 mm long; indusium membranous, semicircular, lacerate, to 3 mm long, to 1.5 mm wide; sporangium long-stalked, uniseriate, 3-seriate below capsule, capsule broadly elliptic in lateral view, with (18-)19(-19) indurated annulus cells, epistomium 2-celled, hypostomium 4-celled. Spores 64 per sporangium, brown, elliptic, monolete, echinate, fenestrate, (38-)41.27(-44) x (26-)28.17(-30) (m. Figure 49E & F.
