Fronds caespitose; stipe with dense lanceolate black or black-brown scales, grooved adaxially; lamina 1-pinnate, oblong, apex acuminate; pinnae alternate or opposite, subspreading, lanceolate, base cuneate or broadly cuneate, usually enlarged to auriculate at acroscopic and basiscopic bases, sessile, pinnatilobate to pinnatifid, apex acuminate; upper pinnae adnate to rachis, lower pinnae slightly shortened; pinna lobes entire or subentire, truncate or rounded, rarely acute at apex; veins not prominent adaxially, visible abaxially, pinnate, veinlets simple, oblique, all reaching laminar margin. Lamina herbaceous, brown-green when dry; rachis stramineous, with dense linear, brown or black scales, grooved adaxially. Sori linear, slightly curved, usually 1-3 per pinna lobe, simple or forked, from midrib to 2/3 of veinlet length; indusia linear, membranous, entire, persistent.
