Description:
Description - Epiphytic or less frequently terrestrial fern. Rhizomes scandent by aerial roots, up to 4 m long, more or less cylindrical, 0.5-1 mm wide, more or less covered with divaricate, ferruginous, attenuate scales that are 3-4 mm long and caudate at the apex. Fronds dimorphic, the sterile ones elliptical or elliptical-lanceolate, 1.5-8 x 1-1.8 cm. Fertile fronds 3.5-10 x 0.3-1.1 cm; stipes slender, 1.5-4 cm long, light brown, glabrous; blades entire, chartaceous, oblong or linear-lanceolate, sparsely covered with minute, ferruginous, subulate scales, the midvein prominent on the lower surface, the secondary venation conspicuous, loosely reticulate, the apex obtuse, the base long-attenuate, the margins entire or slightly crenate. Sori rounded, ferruginous, forming a row on each side of the midvein; paraphyses longer than the sporangia.
Phenology - Found in fertile condition throughout the year.
Conservation Status - Native, quite common.
