Fronds closely clustered, up to 1.5 m long; stipes yellowish, grooved adaxially, about equalling the blades. Blades oblong to ovate-oblong, pinnate, 30-75 cm long, 20-50 cm broad; rhachis grooved on adaxial side, minutely septate-puberulous in the channel; pinnae oblique, the basal pair excavate on the basiscopic side at base and deeply 2-lobate, the lower division shorter than the upper; other lateral pinnae oblong or linear-oblong, acuminate to attenuate-caudate, 1-6 cm broad, sometimes slightly constricted above the inequilateral, semiadnate base, with margins slightly to coarsely sinuate; terminal pinna confluent with the uppermost lateral pinnae; tissue thinly papery, normally glabrous (a pilose variety has been described, but has not been found in Puerto Rico); venation complexly reticulate, the areoles often with a free included veinlet. Sori normally round; indusium persistent, round-reniform, often appearing peltate by overlapping ofthe basal lobes.
