Plants terrestrial. Rhizome rooting at irregular intervals, wide-creeping, irregularly branched, corneus, castaneus, to 4 mm in diameter, initially closely set with scales, glabrous later, scales chartaceus, ferrugineus, lanceolate, cordate to cordate-imbricate, fimbriate, to 5.5 mm long, to 1.2 mm wide. Fronds spaced, to 50 mm apart, erect to scandent, with indeterminate growth; stipe firm, proximally castaneus, stramineous higher up, proximally terete, higher up slightly flattened adaxially, to 1.06 m long, to 4 mm in diameter, initially closely set with scales, glabrous later, scales chartaceus, ferrugineus, lanceolate, ovate-cordate, fimbriate, to 5 mm long, to 1.4 mm wide; lamina pinnately branched, with one or more consecutive storeys of pinna pairs arising from each side of the terminal rachis bud; rachis stramineous to greenish, adaxially somewhat flattened, to 4 mm in diameter, initially densely set with scales similar to those on the stipe; pinnae reniform in outline, to 4 times pseudo-dichotomously branched, with a dormant bud in the axil of each bifurcation, pinna branches all variously pinnatifid, pectinate; pinna-rachis branches stramineous, adaxially shallowly sulcate; ultimate branches adaxially convex, moderately scaled adaxially and abaxially, scales chartaceus, ferrugineus, sessile or short-stalked, linear to lanceolate, long-fimbriate, to 1.6 mm long, to 1 mm wide; segments herbaceous, green adaxially, paler green or glaucous abaxially, linear-acute to linear-obtuse, entire, to 21 mm long, to 3 mm wide, glabrous adaxially, abaxially with stramineous, sessile or short-stalked, long-fimbriate scales. Venation catadromous, evident, pinnately branched or forked, simple at the segment apex. Sori superficial, several pairs on each segment, medial on acroscopic vein branches, with 1-4 sporangia in each sorus, exindusiate. Sporangium stalk multiseriate, short, annulus oblique, complete. Spores monolete, granulate. Figure 10D & E.
