Botanical Description
Shrub
Fern & Moss
Trunk/Bark/Stem
Rhizomes long-creeping, hairy, subterranean. Stipes and rachises pale chestnut-brown at base, yellow-brown at apex, bearing sparse non-glandular hairs or ± glabrous, stipes 15-90 cm long, 3-8 mm diameter, hard.
Leaves
Lamina broadly elliptic or broadly ovate, 25–c. 150 cm long, 20–c. 100 cm wide, 3–4-pinnate at base, glabrous above, with sparse red-brown hairs on midribs and dense colourless appressed non-glandular hairs along veins of undersurface. Longest primary pinnae arising at narrow angles, longest 15–65 cm long, 8–40 cm wide. Secondary pinnae arising at narrow angles; longest 5–26 cm long, 15–130 mm wide; basal one often much-reduced; midribs of primary and secondary pinnae narrowly winged. Tertiary pinnae decreasing markedly in length along secondary pinna; longest 7–70 mm long, 2–20 mm wide, with winged midribs. Quaternary pinnae to 12 mm long and 4 mm wide; ultimate pinnules linear, straight, acute, entire, adnate and decurrent on 1 side. Indusium more than 0.2 mm wide, membranous, entire, glabrous.
