Plants terrestrial, medium-sized. Rhizomes short or shortly creeping with ascending apex, woody, densely clothed with brown linear scales at apex. Fronds caespitose, with radial phyllotaxis; fronds up to 1 m; stipe upward pale purple or brownish, 30-65 cm, base up to 5 mm in diam., triangular in cross section, sparsely scaly, upper part glabrate; lamina imparipinnate, oblong-lanceolate, 35-70 × 16-30 cm, base rounded-cuneate, apex acuminate; lateral pinnae 7-23 pairs, alternate, stalked, ascending, lanceolate, 12-18 × 1.5-2 cm, rounded-cuneate or inequilaterally cuneate at base, incised-serrulate or sharply serrate with beaklike tips at margin, also with few small teeth, apex long acuminate; terminal pinna similar to lateral pinnae, slightly larger, usually with lower part shallowly lobed and segments obtuse-rounded and minutely toothed. Veins free, visible on surfaces, lateral veins pinnate, 3-6 pairs, simple, catadromous, except basal basiscopic veins branched directly from costa, not reaching sinuses between teeth, acroscopic veins branched from base of lateral veins, ending halfway. Lamina papery when dry, dark green, adaxially glabrate, costae occasionally with few brown small scales abaxially; costae grooved adaxially, protuberant abaxially. Sori dense, cinnamon-colored, small, orbicular, abaxial near base or in proximal, occasionally medial places of veins; indusia brown, small, orbicular-reniform, thinly membranous, lacerate as ciliate at margin, fugacious. Spore bilateral, perispore with lophate ridges. 2n = 80.

Damp areas in evergreen broad-leaved forests, among shrubs; 500-1800(-2000) m. Guangxi, Guizhou, SE Xizang, SE Yunnan [Bhutan, W Himalaya, N India, N Myanmar, Nepal, N Thailand].

Hooker and Baker (Syn. Fil. 260. 1867) thought that the type specimen collected from the Kew Garden originated from Sri Lanka, but C. B. Clarke (Rev. Ferns N. India, 513. 1880) disagreed.
