Description: |
Rhizome creeping and branching, 5-8 mm in diameter; rhizome scales reddish-brown, lanceolate, slowly tapering to a point, entire, up to 7 mm long. Fronds closely spaced, erect, herbaceous. Stipe straw coloured to pale green, pink on new fronds, up to 38 cm long, sparsely set with long, pale brown, hair-like scales, more dense so towards the base. Lamina narrowly elliptic to ovate-lanceolate in outline, 26-70 cm × 8-28 cm, 3-pinnatifid to 3-pinnate, lower 4-5 pairs of pinnae reduced in size. Pinnae 6-10 pairs, alternate, set at 80-90° to the rhachis, widest at base, apex tapering to a point. Pinnules unequaly ovate, about twice as long as broad, with acroscopic lobe often enlarged, glabrous on both surfaces, margin deeply pinnatifid to sharply serrate-dentate lobes. Rhachis pale brown, hairless but with few hairlike scales at the base of the pinnae. Sori 0.8-1.5 mm, curved, elliptic to J-shaped; indusium pale brown, erose and membranous. |
Notes: | Could be confused with A. newtonii, which is a forest species with an erect rhizome and basal pinnae that are not or slightly reduced. |
