Information Rhizome up to 4 mm. in diam., creeping, with dark-brown to black multicellular hairs c. 1.5 cm. long. Fronds up to 20 x 0.48 m., climbing. Rhachis up to 3 mm. in diam., twining, matt-pale-brown to greyish-green, producing secondary rhachises up to 10 mm, long, at intervals of 7–20 cm. each with an aborted apical bud densely clothed with brown multicellular hairs, 1.5 mm. long. Pinnae (secondary rhachis-branches) triangular, 2-pinnate to 3-pinnatifid. Secondary and tertiary rhachises with narrowly winged, petiolate, not articulated, lanceolate-oblong to lanceolate, simple to 2-pinnatifid sterile pinnules up to 11 cm. long, the ultimate segments usually with prominent basal lobes, apices broadly acute, margins both coarsely crenate and with crenations finely crenate, veins hairy on both surfaces. Fertile pinnules up to 9 cm. long, lanceolate, simple to 2-pinnate, usually with a long apical segment and shorter basal segments, veins hairy on both surfaces, margin crenate but produced into numerous linear fertile lobes up to 6x1 mm., often at irregular intervals.
