Common names:
Status: Native
Rhizome erect, up to 10 mm thick; scales c. 3 mm long, brown, entire, subulate. Fronds tufted, proliferous near the apex, the apical segment above the proliferating bud has more than 5 lobes. Stipe up to 20 cm long, stipe and rhachis sparsely set with dark brown scales. Lamina 22-42 cm × 4.5-13 cm, 2-pinnatifid, lanceolate to narrowly elliptic in outline. Pinnae with 6 or more basiscopic pinnae lobes; the first arissing between the 1st-2nd acroscopic lobes. Pinnae variable, from shallowly incised to strongly pinnatifid into narrow simple bifid lobes, basal lobe pointing towards the apex free, 4-fid and larger than the other lobes. Sori one per lobe, linear, set along the veins, indusiate.   
Notes: Confused with A. dregeanum; A. preussii has the first basal lobe arising between the 1st and 2nd acroscopic lobes.
