Habit, rhizome morphology. Plants forming tufts of 5 or 6 fronds. Runners often proliferous, 0.5-1 mm thick (or thinner), branching angle narrow. Scales on runners sparse, spreading. Tubers absent. Fronds 25-34 by 3-4 cm, stipe 3-8 cm long. Lamina base strongly reduced, tapering over 8-10 cm, reduced basal pinnae 0.9-1.1 cm distant, middle pinnae straight. Sterile pinnae 1.4-2 by 0.3-0.5 cm, leathery, base fully 1-sided, basiscopic base narrowly cuneate, acroscopic base emarginate, cuneate or truncate, distinctly auricled, margin in basal part crenate, towards apex deeply dentate or incised, apex rounded or obtuse. Fertile pinnae 2 by 0.3-0.4 cm, more sinuose between the sori than the sterile pinnae. Indument. Basal scales peltate or type of attachment indistinct, spreading, 4 by 0.25 mm (or less), central part light brown, dull, margin not hyaline, in basal part irregularly lacerate, in acumen entire, without glands, apex acumen narrow, often sinuous, tapering to a long narrow apex. Rhachis scales sparse (often caducous), with a well-developed protracted acumen, spreading, dark (distinctly darker than the basal scales), acumen entire. Scales on lamina absent. Hairs on lamina absent. Sori submarginal or medial, elongated. Indusium lunulate, attached at broad base.
