Rhizome 1-1.25 mm ø; scales to 2.5 mm long, otherwise as in var. pulchella. Petioles c. 10-20 cm long, 0.5 mm ø, adaxially flattened or shallowly sulcate, pale at least above, abaxially dark, rounded, bi-angular at least near the apex. Lamina c. 20-35 cm long, 2-3 cm wide, with c. 25-50 pinnules to a side; rachis abaxially dark, bi-angular, sometimes pale-angled, upward usually pale and sulcate, adaxially pale, sulcate. Pinnules herbaceous or usually subcoriaceous, dark brownish when dry, usually everywhere sclerotic-margined, somewhat ascending, not contiguous, ligulate, the larger ones 10-16 by 4-6 mm (2-)2.5-3 times as long as wide; upper margin with 2-4 narrow major incisions to 2 mm but usually only 1 mm or less deep, sometimes with some smaller additional ones, the lobes rounded, often with one or more teeth. Basal pinnules often more remote but scarcely reduced, upper pinnules gradually and strongly reduced, as in var. pulchella. Veins immersed, not evident, simple or once forked, lax, 1-2 mm apart. Sori uni-or binerval, usually with distinctly concave base, 3/4-2 mm long; indusium pale, rather rigid, subentire to dentate or lobed, subhippoerepi-form to crescent-shaped, narrowed at the free sides, usually strongly intramarginal but sometimes with protruding lobes, 0.3-0.5 mm wide, often reflexed at maturity.
