Description:
Species Description - Terrestrial or epilithic fern, 15-30 cm tall. Rhizome decumbent to erect, densely clothed with pale greenish to pale brownish, linear, hair-pointed scales to 5 mm long. Fronds prostrate to ascending or arching, mostly 20-100 cm long; stipes pale brown, grooved along upper surface, much shorter than the blades and densely clothed with pale, hairlike scales. Blades usually 6-25 cm broad or more, oblanceolate to narrowly obovate, attenuate at base, at apex terminating abruptly in a long, linear pinna, usually larger than the lateral ones; lateral pinnae narrowly lance-linear, the bases often slightly dilated, the margins (without sori) finely and sharply serrulate; tissue thin-herbaceous, bright green, glabrous, the veins free, raised, mostly 1-forked near base. Indusium firm, greenish brown, entire or slightly wavy.
