In most respects like a subbipinnate form of L. orbiculata, characterized by the following combination of characters: Rhizome scales castaneous, very narrowly triangular, to 3 mm long, to 6-seriate at base, a considerable apical part uni-and biseriate. Lamina subcoriaceous to coriaceous; at least some leaves of each plant subbipinnate, with a few paucijugate pinnae at base, rarely the basal pinnae more fully pinnate; terminal pinnules of lateral pinnae large, flabellate-suborbicular. Petiole and rachis dark, abaxially terete or the rachis obtusely bi-angular; secondary rachises abruptly pale. Sterile margin less acutely dentate. Spores c. 30 μ.
