Characteristics

Plants evergreen, small to medium-sized. Rhizome slender, creeping, brown, ca. 3 mm in diam., densely scaly at apex; scales brown, lanceolate, ca. 3 mm, thickly membranous, entire; fronds distant, 5-10 mm apart. Fertile fronds up to 60 cm; stipe dark brown at base, upward green-stramineous, 25-30 cm, ca. 3 mm in diam., base sparsely scaly with brown, linear scales, upward glabrous, narrowly grooved adaxially; lamina 1-pinnate, broadly lanceolate, 30-35 × 8-14 cm, apex caudate and long acuminate; pinnae up to 18 pairs, alternate, subspreading, 1.5-3 cm apart, sickle-shaped lanceolate, 4-9 × 1-1.5 cm, with stalk 1-2 mm, asymmetrical, basiscopic base cuneate, acroscopic base deltoid-auriculate, margin biserrate or uniserrate (var. parawichurae), except a few distal pinnae, apex acuminate to caudate or acute or subrounded (var. parawichurae); costae narrowly winged; veins raised abaxially, impressed adaxially, unequally forked into 3-5 simple veinlets, anadromous, ascending, all reaching serrate margin. Lamina stiffly papery or subleathery, light green when dry, glabrous on both surfaces; rachis green-stramineous, glabrous, shallowly grooved adaxially. Sori shortly linear, 2.5-7 mm, straight or slightly falcate, up to 16 pairs per each pinna, in 1 row on each side of costa, close to costa, mostly single, rarely double, occasionally 1 or 2 pairs in basal auricle; indusia brown, long, membranous, entire, persistent; spores elliptic in polar view, reniform in equatorial view, perispore hyaline, few flakelike rugate. 2n = 82.
