Fronds laceolate-elliptic, the basal pinnae somewhat reduced, the apical pinna gradually so, bipinnate, the pinnules adnate and sometimes constricted basally, the pinnarachis with a narrow green wing, the ultimate segments serrate, costate, thick and coriaceous, the veins free, once-forked, the acroscopic branch terminating in a tooth; the basal pinnules of the lateral pinnae fertile, not or hardly contracted. Sporangia not grouped into sori, +/- crowded on both branches of the veins, large, +/- globose, on short, thick stalks, dehiscing from the annulus over the apex, the annulus a group of thickened cells to one side, exindusiate, paraphyses absent.
