Rhizome short, erect; oblong-lanceolate with long tail, up to 25 by 5 mm, brown to dark, membranous, entire. Stipe stramineous, densely scaly at base, more sparsely upwards, up to 60 cm long. Lamina pinnate, lanceolate, caudate-acute at apex, slightly narrowing at base, up to 85 by 45 cm; rachis grooved on upper surface, densely scaly throughout with narrow, brown to nearly black scales up to 8 mm long; pinnae more than 20 pairs, lower pinnae falcate, linear-lanceolate, caudate-attenuate, truncate or subcordate at base, subsessile or very shortly stalked, up to 20 by 2 cm, lobed to quarter way towards costa, upper pinnae gradually becoming smaller upwards, decurrent at base; costa nearly at right angle to rachis, distinctly raised on lower surface, grooved above; lobes subdeltoid, oblique, round to acute at apex, entire, up to 5 by 6 mm; chartaceous, deep green, glabrous. Sori in two or three indistinct rows near costa, leaving marginal half of lamina sterile, indusiate; indusia round-reniform, small, fugacious, glabrous. On humus-rich mountain slopes in light or deep shade at 1200–1600 m alt. Thailand, Sri Lanka, S. India, W. Malaysia, Sumatra, Java (type), Borneo and the Philippines.
