Habit, rhizome morphology. Runners 1-1.5 mm thick, branching angle narrow. Scales on runners very sparse or sparse, appressed. Tubers absent. Fronds 65-200 cm long (or more), 7-10 cm wide, stipe 10-34 cm long. Lamina base strongly reduced, tapering over 20-35 cm, basal pinnae 0.7-1 cm long, 1.5-3.5 cm distant, middle pinnae distinctly to strongly falcate. Sterile pinnae 4-8 by 1-1.4 cm, herbaceous, thick, base strongly unequal, basiscopic base rounded, acroscopic base truncate, slightly to distinctly auricled, margin in basal part crenate, dentate or serrate, apex acute to (indistinctly) 1 cm caudate. Fertile pinnae 4.8-8 by 0.7-1.2 cm, otherwise similar to sterile ones. Indument. Basal scales peltate, appressed, 2 by 0.5-1 mm, central part blackish, shining, hyaline margin narrow, marginal glands absent, margin in basal part irregularly lacerate or ciliate, acumen ciliate. Rhachis scales dense, with a well-developed protracted acumen, squarrose to recurved, dark, with entire acumen. Scales on lamina usually persistent, with a long, narrow, entire, acicular acumen. Hairs on lamina and costa absent. Sori submarginal, 19-29 pairs on fully fertile pinnae, round, not impressed. Indusium reniform, with narrow sinus, attached at sinus.

It is a tropical plant. It grows near rivers and in wet places.

It can be grown from spores but also by shoots of the stolons or runners.
