Characteristics

Plants terrestrial, 60-90 cm tall. Rhizome erect or ascendant, short, stout, densely scaly at apex and stipe bases; scales dark brown, linear-lanceolate, ca. 5 mm, membranous, entire, apices capillaceous. Fronds clustered; stipe stramineous, 30-50 cm, 5-6 mm in diam. at base, grooved above, sparsely covered with light brown and articulate hairs, glabrous beneath. Lamina 2-pinnate to 2-pinnatifid at base, pinnate upward, dark green when dried, deltoid-ovate, 35-45 × 25-40 cm, papery, abaxially glabrous, adaxially hairy, base slightly cordate, apex acuminate; rachises and costae stramineous, densely hairy; lateral veins slightly flexuose, raised below, sparsely covered with light brown articulate hairs; pinnae 2 or 3 pairs, subopposite at base, alternate upward; basal pinnae largest, stalks 2.5-4 cm, deltoid, ca. 22 × 10-12 cm, pinnate with 2 or 3 separate pinnules, basal basiscopic pinnules up to 12 cm, terminal pinnules 13-15 × ca. 6 cm, bases cuneate, apices long acuminate; secondary pinnae broadly falcate-lanceolate, 15-20 × 3-5 cm, stalk ca. 1 cm, bases cordate, apices long acuminate, margins coarsely sinuate to sinuate-dentate, dentation (lobes) triangular; terminal pinna hastate, up to 20 cm at apex, base cuneate to slightly decurrent, apex long acuminate, pinnatilobed, basal lobes ovate-lanceolate. Veinlets forming subhexagonal areoles with cross veins, included veinlets forked, obscure adaxially, slightly raised abaxially. Sori orbicular, small, located at coupling veinlets, in irregular rows between adjacent lateral veins, near margin of lobes; indusia brown, small, clypeate, entire, persistent.
