Characteristics

Plants evergreen. Rhizome ascending, short, ca. 8 mm in diam. including stipe bases. Fronds few, 9-35(-40) cm; stipe stramineous, 6-16 cm, slender, 0.6-0.9 mm in diam. at base; basal stipe scales sparse, dark brown, lanceolate and subulate, membranous, margins irregularly ciliate; distal stipe scales sparser. Lamina 1-pinnate, yellowish green or green, adaxially shiny, narrowly elliptic-lanceolate, 7-22 × 3-8 cm at middle, slightly contracted toward base, 1.5-3 cm wide at base, acute; rachis stramineous, without proliferous bulbils, sparsely scaly; scales similar to stipe scales but smaller. Pinnae 8-12 pairs, alternate, approximate by a distance equal to or narrower than pinna width, rarely approximate, ascendant, sometimes lower pairs angled slightly basiscopically, stalked, oblong, deltoid, deltoid-lanceolate, or ovate, middle pairs 2.6-4.5 × 1-1.6 cm, basalmost pairs 1.5-3.4 cm × 1-1.3 mm, margins irregularly lobed, incised to pinnatisect with free lobes, apices obtuse; acroscopic margins forming a 60° angle with rachis, basiscopic margins forming a 120° angle with rachis. Lobes 0-3 pairs, obovate, bases broadly cuneate, apices acute or acuminate; basal acroscopic lobes obviously largest, free or nearly free, other lobes not free, margins repand, without teeth or spinules; adaxially glabrous, abaxially sparsely scaly; microscales light brown, nearly linear; frond texture thickly papery. Sori small, ca. 1 mm in diam., terminal on veinlets, closer to lobe or pinna margin; indusia small, slightly erose.
