Information Epiphytic; rhizome erect, ± 1 cm diameter, covered with old stipe bases with greyish-brown, lanceolate-subulate, subentire scales up to 10x1.5 mm, composed of clear thin-walled cells, attenuate into a hair-like tip. Frond tufted, erect, not proliferous. Stipe matt-grey-green to brown, 5–30 cm long and 3 mm diameter, subglabrous, with a few scales towards the base similar to the rhizome scales. Lamina dark shiny green, herbaceous to coriaceous, 18–40x10–19 cm, oblong, erect, 1-pinnate; basal pinnae not reduced, terminal pinna similar to lateral ones. Pinnae in 2–9 sub-opposite pairs with a terminal pinna similar to the other pinnae, petiolulate, lanceolate to oblong, 8–14x1.8–2.5 cm, the terminal pinna 14–16x2.5–3.5 cm, acroscopic base cuneate and often parallel to the rachis, basiscopic base attenuate-cuneate, margin irregularly and shallowly undulate-crenate, attenuate to acuminate, glabrous; veins ending short of the margin. Rachis matt-purplish-brown, at first set with dark irregularly fimbriate scales up to 2 mm long, later becoming glabrous. Sori many, along the veins at 45° angle to costa, extending from near the costa to more than halfway to the margin, (4–)9–13 mm long; indusium membranous, entire, 0.5–0.8 mm wide. Fig. 6: 1–2, p. 37.

Information Epiphyte or less often terrestrial; rhizome to 2 cm diameter, erect, with pale brown to brown concolorous lanceolate scales 6–12x1.5–3.5 mm, acute to acuminate, margin with thin lobes (‘fimbriate’). Fronds tufted, erect or arching, not proliferous. Stipe matt-purplish-brown, 13–48 cm long, to 4 mm diameter, glabrous except for a few scales at the base similar to those on the rhizome. Lamina ovate to ovate-elliptic, 20–88x8–32 cm, 1-pinnate, with the basal pairs of pinnae somewhat reduced, terminal pinna large and similar to laterals, 5–12x1.6–2.5 cm. Rachis glabrous or with few very narrow scales to 1 mm. Pinnae in 7–20 pairs, narrowly lanceolate and a bit falcate, the largest 5–16x1.5–3 cm, apex acuminate or acute, base truncate and parallel to rachis on the acroscopic side, oblique on the basiscopic side, margin regularly crenate with a vein ending in each crenation, glabrous above but with a few scattered minute branched linear scales on the costae and veins below. Rachis glabrous. Sori many per pinna, at 45° to costa, extending from near the costa to 1/2 way to the margin, 2.5–6 mm long; indusium membranous, to 1.2 mm wide, entire. Fig. 6: 3–4, p. 37.
