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.
