Venation evident or obscure, forked, in the sterile frond the free branches end near the margin in an enlarged apex; in the fertile frond the veins form a near-marginal vascular commissure with short excurrent veins extending from it. Sori linear, extending most of the pinna length; indusium firm, brown, linear, repand; sporangium long-stalked, simple, 3-seriate below capsule, capsule broadly elliptic in lateral view, with (12-)13(-14) indurated annulus cells, epistomium 4(-5)-celled, hypostomium 4(-5)-celled. Spores elliptic, monolete, with low, irregular verrucae, (36-)39.3(-42) x (26-)28(-32) µm.
Perennial with branched rhizome and stolons. Fronds erect or arching, to 40 cm long, stipe sparsely scaled, lamina herbaceous, narrowly elliptic, to 35 cm long, 1-pinnate, sterile pinnae oblong-acute, mucronate, base somewhat auriculate, fertile pinnae linear-auriculate, falcate. Sori extending most of the length of fertile pinnae, indusium lacerate.
Perennial with branched rhizome. Fronds erect to arching, firm, dimorphic, stipe sparsely scaled, lamina narrowly elliptic, up to 640 mm long, 1-pinnate, sterile pinnae oblong-acute, mucronate, base somewhat auriculate, up to 25 mm long, fertile pinnae linear, falcate, up to 40 mm long.
