Characteristics

Plants evergreen, medium-sized. Rhizome erect, black, ca. 1 cm in diam., with dense black-brown, stiff, fleshy, long, stout roots, apex scaly; scales dark brown, lanceolate, ca. 4 mm, margin toothed; fronds caespitose. Fertile fronds up to 80 cm; stipe brown at base, upward green-stramineous, up to 40 cm, ca. 3 mm in diam., base sparsely scaly, scales similar to those on rhizome, upward glabrous, shallowly grooved adaxially; lamina 1-pinnate, downward pinnatilobate to pinnatisect, ovate or ovate-oblong, up to 40 × 20 cm, apex abruptly narrowed, acuminate; lateral pinnae up to 10 pairs, alternate, ascending, sickle-shaped lanceolate, up to 15 × 3 cm, base cuneate, symmetrical, margin broadly shallowly serrate, apex acuminate; basal 3 or 4 pairs of pinnae with stalk ca. 2 mm, upward gradually sessile. Veins visible, pinnate, veinlets 3 or 4 pairs per vein, simple, markedly ascending. Lamina stiffly papery, mostly gray-green on adaxial surface, light gray-green abaxially, glabrous on both surfaces; rachis stramineous or light green stramineous, glabrous, shallowly grooved adaxially. Sori linear, up to 8 mm, usually 2 pairs per vein, simple or double on basal acroscopic veinlet, from base of veinlet or near base upward ascending, not reaching pinna margin; indusia light brown, linear, membranous, entire, persistent. Spores bean-shaped, perispore thin, with prominent and average large aperture ornamentation.
