Information
Rhizome erect or shortly creeping, with lanceolate scales 4–10 mm long, black in centre with chestnut or pale margins. Fronds 10–30, tufted, 5–50 cm tall; stipe 1–16(–30) cm tall; stipe and rhachis black, glabrous or finely orange-brown puberulous on upper surface; lamina blue-green, glaucous, ovate-lanceolate to narrowly triangular in outline, 13–43 cm long, 5.5–25 cm wide, (1–)2-pinnate, often the lower pinnae 2-pinnate, hence lamina incompletely 3-pinnate; very young plants have a single round pinnule; pinnae oblong in outline, 1.5–6 cm long with (1–)3–11 pinnules, the stalks (2–)5–12 mm long; upper pinnae reduced to 1 pinnule; ultimate pinnules triangular, elliptic or ± round, often slightly hastate to distinctly hastate, 0.6–5.4 cm long, 0.4–5.2 cm wide; stalklets black, 0.5–26 mm long; veins free but not visible without clearing. Sori and indusium continuous.
