(A natural hybrid between this species and A. beckleri has been incorrectly known as A. palisotii, which is confined to Nth Qld.)

The small fronds of the juvenile stage contrast with the much larger fronds of the mature plant.

Widespread in rainforest, growing on rocks or trees. Rhizome very long-creeping, rigid, to 6mm thick, densely covered with brown scales. (PlantNet)

Slender climbing fern growing over rocks and tree trunks by means of a rusty, fibrous, creeping root stem. Leaves compound, pinnate, (or pseudo-pinnate), alternate, arising directly from the root stem, divided into 9 alternately arranged, dark green, glossy leaflets, (light green in new growth), elliptic to ovate 2-5cm long x 1.5-3cm wide, base broadly cuneate, sometimes oblique, apex drawn out to a blunt or fine point. Lateral leaflets with small petiolules 2-3mm long, the terminal leaflet stalk markedly longer. Midveins prominent, secondary veins faint, parallel and curving out to the margins. Rachis green and faintly zigzag. Moist forest shade, rarely in the open margins. Mt Glorious (Maiala NP).

Slender, wiry climbing fern, climbing by means of rusty, fibrous, adventitious roots and often forming large, tangled masses on forest tree trunks. Leaves compound, pinnate (or pseudo-pinnate), alternate, arising directly from the root stem and divided into 15-19, alternately arranged, dark green, glossy leaflets, 5-15cm long x 1-1.5cm wide, lanceolate, apex acuminate, drawn out to a long, tapering fine point, base sometimes rounded but more often markedly oblique; margins entire or crenulate. Lateral leaflets with small petiolules 2-3mm long, the terminal leaflet stalk always longer. Midveins prominent, dark, secondary veins indistinct. Rachis dark greenish black and slightly zigzag. Fertile fronds not observed. Moist forest shade, rarely in the open margins. Mt Glorious (Maiala NP).
