Plants evergreen. Rhizome erect, short, together with persistent stipe base ca. 1.5 cm in diam. Fronds 10-20 cm; stipe stramineous, 2-6 cm, thinner than 1 mm in diam., whole stipe sparsely scaly; scales brownish yellow, broadly lanceolate or broadly ovate-lanceolate, thinly membranous, with a few long teeth. Lamina 1-pinnate, yellowish green when dry, narrowly elliptic-lanceolate or only linear-lanceolate, 7-13 × 1-2 cm, base slightly contracted or gradually contracted below middle, apex long acuminate; rachis stramineous, without proliferous bulbils, sparsely scaly; scales similar to basal stipe scales. Pinnae 10-23 pairs, attached at nearly right angles to rachis, ovate or ovate-oblong, apices acute, sessile, margins pinnatilobate or only sparsely toothed, teeth shortly spinulose, bases asymmetrical, acroscopic base ± auriculate, auricles of lower pinnae with 2 or 3 acute teeth, acroscopic margins mostly attached at acute angles to rachis and ascendant, basiscopic margins obliquely truncate, attached at nearly right angles to rachis and angled basiscopically, middle pinnae 5-9 × ca. 4 mm, basal pinnae often obviously contracted and ca. 3 mm long and wide; margins of lower lobes often with 2 or 3 acute teeth; frond texture thinly papery. Sori abaxial on veinlets, medial or closer to pinna margin, mostly 2-4 per pinna; indusia small, evanescent.
