General Information

Plants summer-green. Rhizome slender, creeping, apex with yellow-brown, broadly lanceolate or lanceolate scales; fronds distant to approximate. Fertile frond up to 1 m; stipe scaly and hairy; lamina bipinnatilobate, oblong or broadly oblong-lanceolate, sometimes triangular, base slightly or not reduced, apex long acuminate or abruptly narrowed, acuminate; pinnae 4-8 pairs, oblique or occasionally spreading, straight or subfalcate, oblong-lanceolate or lanceolate, base subtruncate, apex long acuminate or caudate; pinna lobes 5-18 pairs, oblique at angles of 40°-45°, rectangular or oblong, or falcate-lanceolate, margin sparsely dentate or repand, rarely shallowly lobed, apex subtruncate or rounded to acute; veins pinnate with less than 8 pairs of veinlets, oblique, forked or simple, often not prominently adaxially, slightly visible abaxially. Lamina herbaceous, rachis with sparse pale brown lanceolate scales and nodose soft hairs, costae and veins with nodose hairs on both sides. Sori shortly linear, straight, mostly single, medial, double on basal acroscopic veinlets; indusia pale brown, membranous, glabrous, margin lacerate, incurved when young. n = 120 (6´).

      Plants terrestrial or epilithic. Rhizome wide-creeping, sparsely branched, to 120 mm long, to 5 mm in diameter, set with roots, widely spaced persistent stipe bases and scales, scales chartaceous, castaneous to ferrugineous, adnate, lanceolate to narrowly ovate, entire or with scattered unicellular glandlike cells along the margin, apex terminates in an oblong thin-walled cell, to 5 mm long, to 1 mm wide. Fronds erect to arching, to 15 mm apart, to 6 per plant; stipe firm, atrocastaneous, adaxially shallowly sulcate, to 300 mm long, to 2.2 mm in diameter, closely set with scales and hairs, scales similar to those on the rhizome, hairs pluricellular, uniseriate, acicular, or cylindrical, terminating in a gland-like cell, to 0.8 mm long; lamina anadromous, catadromous towards the apex, 1-pinnate- pinnatifid, ovate, to 310 mm long, to 280 mm wide, with up to 6 petiolated pinna pairs, becoming sessile and adnate towards the apex; rachis shallowly sulcate adaxially, densely set with scales and hairs similar to those on the stipe; pinnae opposite to alternate, pinnatifid, basally more widely spaced, basal pinnae not reduced, narrowly lanceolate to oblong-acuminate, basal pinna pair often basiscopically developed, to 168 mm long, to 40 mm wide; costa adaxially shallowly sulcate, closely set with scales and hairs similar to those on the rachis; pinnules firmly herbaceous, oblong-cuneate to oblong-obtuse, to 31 mm long, to 10 mm wide, crenulate, adaxially regularly set with pluricellular acicular hairs along and between the veins, abaxially moderately set with acicular hairs along the veins, to 1 mm long. Venation evident, pinnately branched, free, branches end in the teeth near the margin. Sori linear, often back-to-back, usually on the acroscopic vein branches, to 3 mm long; sporangium long-stalked, simple or with 1 or 2 gland-like cells near the apex, capsule globose in lateral view, with (13-)14(-15) indurated annulus cells, epistomium (3-)4-celled, hypostomium (3-)4-celled; indusium chartaceous, stramineous, linear, fimbriate, often with acicular and cylindrical hairs terminating in an enlarged gland-like cell occurring on the surface, to 3 mm long, to 0.3 mm wide. Spores brown, ellipsoidal to spheroidal, monolete, tuberculate, exospore (30-)35.8(-40) x (24-)26.6(-28) µm.
