Plants epilithic to epiphytic. Rhizome erect, to 25 mm long, to 5 mm wide, set with roots, crowded persistent stipe bases and scales, scales chartaceous, concolorous or bicolorous, if bicolorous then centrally atrocastaneous, margins ferrugineous, clathrate, sessile, lanceolate to ovate, cordate-imbricate, margins set with uniseriate, pluricellular outgrowths, apex terminates in an oblong thin-walled cell, to 4 mm long, to 1.4 mm wide. Fronds crowded, caespitose, suberect to arching, to 280 mm long; stipe firm, green, basally sulcate, sulcus centrally ridged higher up, to 125 mm long, to 1.3 mm in diameter, initially moderately scaled, scales chartaceous, sessile, ferrugineous, clathrate, ovate to lanceolate, margins regularly set with long pluricellular outgrowths terminating in an enlarged, obovate gland-like cell, apex terminates in an enlarged gland-like cell, to 4 mm long, to 1.2 mm wide; lamina anadromous, to 2-pinnate, lanceolate to narrowly ovate, to 170 mm long, to 55 mm wide, with up to 13 pinna pairs; rachis firm, green, sulcate, centrally ridged, initially moderately scaled, scales similar to those on the stipe; pinnae petiolate, petiole to 4 mm long, opposite to alternate, basally often more widely spaced, the basal 2 or 3 pairs gradually reduced or not, coriaceous, lanceolate, ovate, narrowly elliptic to linear, to 38 mm long, to 15 mm wide, with up to 4 pinnule pairs; pinna-rachis sulcate, centrally ridged, the ridge not confluent with that of the rachis, sparsely set with scales similar to, but smaller than those on the rachis; pinnules alternate, spaced, obliquely spatulate or forked into lobes, to 10 mm long, to 1.2 mm wide, glabrous adaxially, abaxially sparsely set with scales similar to, but smaller than, those on the rachis, to 1.3 mm long. Venation anadromous, obscure, ending near the margin. Sori cupuliform, borne terminally on each lobe, acentric, to 1.5 mm long; receptacle with simple, pluricellular, hair-like paraphyses, apical cell acicular, to 1.4 mm long; indusium membranous, entire, to 1 mm wide; sporangium long-stalked, uniseriate, 3-seriate below the capsule, capsule broadly elliptic in lateral view, with (17-)19(-22) indurated annulus cells, epistomium 2-celled, hypostomium (3-)4-celled. Spores 64 per sporangium, brown, elliptic, monolete, perispore folded into narrow reticulate ridges, erose, the areolae fenestrate, exospore (44-)49.52(-54) x (28-)31.7(-36) µm.
