General Information

Plants terrestrial, 1.2-1.5(-2) m tall. Rhizome creeping, more than 7 mm in diam., glabrescent. Fronds scattered; stipe straw-colored, ca. 50[-70] cm, stiff, usually with dense, short, gray-brown, segmented hairs; rachis and rachillae also straw-colored, with scattered soft hairs. Lamina yellow-green when dried, 3- or 4-pinnate, ovate-oblong in outline, 60-100 × 30-40[-50] cm, thinly papery, both surfaces with often dense, adpressed, slender hairs, base wider, gradually shorter distally, apex acuminate; pinnae 10-15[-20+] pairs, alternate, 10-15 cm apart, spreading obliquely upward, with stalk 1-1.5 cm, bipinnate, broadly lanceolate in outline, lowermost pinnae slightly smaller, largest pinnae 28-30 cm, 10-15 cm wide at base, apex long acuminate; pinnules 15-20 pairs, upswept, parallel with rachis, broadly lanceolate, 2.5-4 × 0.8-1 cm, pinnatisect almost to rachillae, base unequal in width, decurrent, cuneate basiscopically, subtruncate acroscopically, apex acuminate; distal lobes 6-8 pairs, suprabasal ones longer, parallel with rachillae, others oblong, 7-8 × ca. 4 mm, truncate acroscopically, straight-cuneate basiscopically, margin obtusely pinnatifid, apex rounded; lobules entire or apex with 2 or 3 dwarf obtuse teeth. Veins slightly prominent abaxially, pinnately branching. Sori near notch at margin of lobules; indusium brownish, shallowly saucer- or fan-shaped, small, firm, densely hairy.

    Plants terrestrial. Rhizome subterranean or epigeal, wide-creeping, irregularly branched, set with roots, widely spaced persistent stipe bases and hairs, the hairs ferrugineous, simple, pluricellular, uniseriate, to 2.8 mm long. Fronds spaced, to 35 mm apart, erect, to 2.07 m long; stipe firm, proximally castaneus, stramineous to greenish higher up, terete, to 475 mm long, to 7 mm in diameter, closely set with hairs similar to, but shorter than, those on the rhizome; lamina anadromous, ovate to oblong-ovate, to 3-pinnate-pinnatifid, to 2.6 m long, to 1 m wide, the basal 1 to 2 pinna pairs reduced or not, with up to 25 pinna pairs; rachis and lower order axes stramineous, shallowly sulcate adaxially, sulci not confluent, closely set with hairs similar to those on the stipe; pinnae petiolate, petiole to 12 mm long, alternate, basally spaced, slightly overlapping apically, to 2-pinnate-pinnatifid, often slightly basiscopically developed, oblong-cuneate to narrowly elliptic, to 535 mm long, to 135 mm wide, with up to 24 pinnule pairs; pinnules petiolate, petiole to 1.5 mm long, alternate, basally spaced, slightly overlapping towards the apex, several basal pairs often reduced, to 1-pinnate-pinnatifid, usually slightly acroscopically developed, triangular, oblong-cuneate, or ovate, to 77 mm long, to 32 mm wide, with up to 8 petiolated and sessile segment pairs; segments petiolate, petiole to 1 mm long, alternate, basally spaced or overlapping, adnate towards the apex, pinnatifid to lobed, acroscopically developed, inequilaterally ovate to oblong-obtuse, to 17 mm long, to 8 mm wide, lobes shallowly dentate, adaxially closely set with hairs along the veins, the hairs hyaline to stramineous, acicular, pluricellular, uniseriate, to 0.5 mm long, abaxially closely set with similar hairs along and between the veins. Venation pinnately branched, vein branches end in the margin in the sinus between the teeth, sorus-bearing veins abbreviated, the endings enlarged. Sori circular, terminal on primarily the acroscopic anadromous vein branches of the segments, to 1 mm in diameter; receptacle paraphysate, paraphyses simple, pluricellular, uniseriate, apical cell elliptic, gland-like, to 320 mm long; sporangium short-stalked, simple, capsule broadly elliptic in lateral view, with (16-)18(-22) indurated annulus cells, epistomium (4-)5(-7)-celled, hypostomium (4-)5(-6)-celled; indusium cup-shaped, membranous, to 1 mm wide, opening outwards. Spores 64 per sporangium, stramineous, tetrahedral-globose, prominently lobed, echinulate, (32-)35.72(-38) µm in equatorial diameter.
