Information Rhizome up to 7 mm. in diam., short, creeping, with tufted fronds and with linear-attenuate subentire dark-brown shining rhizome-scales up to 4.5 mm. long. Stipe ebeneous, up to 20 cm. long, terete, glabrous except for a short pubescence on the ventral surface in the upper half. Frond erect and arching, coriaceous. Lamina up to 36 x 34 cm., triangular in outline, 2-pinnate with the basal pinnae developed basiscopically; upper pinnae and pinnules of lower pinnae up to 6.5 x 1.5 cm., lanceolate, sometimes falcate, entire, attenuate, with cordate bases articulated to the apices of their petioles or petiolules; veins anastomosing, obscure; rhachis and secondary rhachises ebeneous, shortly pubescent ventrally, glabrous dorsally. Sori forming a marginal soral line; indusium continuous, entire, membranous.

Information Rhizome short-creeping with linear pale chestnut to dark brown subentire scales; scales up to 4.5 mm long, shining and finely attenuate, with very narrow pale margins. Fronds 4–8, tufted, 10.5–90 cm tall; stipe purplish black, 6–50 cm long, glabrous except for scales at extreme base; lamina ± triangular in outline, 4.5–40 cm long, 13–34 cm wide, (1–)2-partially 3-pinnate (some simple pinnate fronds may be present); pinnae in 6–12 pairs, the upper 5–8 simple, the lower 2–5 up to 14 cm long, pinnate with 5–7 pairs of pinnules, the lower 1–2 basiscopic pinnulessometimes again pinnate with 3 pairs of ultimate segments; segments (pinnae, pinnules or ultimate segments according to position) narrowly triangular from a shortly cordate to rounded base to a usually narrow apex, 0.8–7.2(–8) cm long, 0.7–2.3(–4) cm wide, often curved, rarely hastate; rhachis purplish black, very shortly bristly pubescent on upper surface; stalklets same colour as rhachis, 1–4 mm long (apical one 8 mm); veins not easily visible but often so with ordinary transmitted light, strongly anastomosing; sterile margins crenate-dentate. Sori and indusium continuous.
