Habitat

Coastal to montane. Usually in forest, especially lowland, riparian forest.

Features

Rhizome short-creeping, 5–8 mm diameter, densely scaly and hairy; scales 4.0–9.6 × 0.5–1.0 mm, dark red-brown to red-black, bristly, persistent. Fronds crowded. Stipe 100–480(–500) mm long, densely invested in harsh, bristly, stiff red-brown scales 4.0–9.6 × 0.5–1.0 mm and shorter, glandular hairs. Lamina 3–4-pinnate, deltoid, 100–500 × 60–300 mm, dark brownish green, rugose, glabrous except on veins and midribs; these invested in black bristly scales and smaller brown hairs; rachis bearing red-brown bristly scales and hairs; primary and secondary pinnae stalked, finely dissected. Ultimate segments narrowly oblong-lanceolate, sharply toothed; margins thickened with deeply cut into narrow curved teeth. Sori medial on the veinlets, or at the fork of these; indusium pale brown.
