Fronds sessile, 70–170 by 20–45(–60) cm, lobed almost to rachis, lobes continuing with wings less than 1 cm broad, the base of laminae broadly rounded to cordate, up to 15 cm broad, subentire or shallowly lobed, brown, like the nest leaves of Drynaria; lobes of the upper part of laminae ascending, usually more than a dozen pairs, linear-subtriangular, attenuately acuminate at apex, entire at margin, 15–40 by 1.5–5 cm, every lobe falling at the abscission along rachis; veins raised on both surfaces, venation drynarioid, or reticulate, main areoles quadrangular, smaller areoles with free included veinlets; coriaceous, green, glabrous. Sori one, or very rarely two, row(s) between main veins, more or less elongate, or sometimes uniting longitudinally, but rarely continuous beyond cross veins.2
