Description:
Rhizome erect, up to 12 mm in diameter; scales dark brown, lanceolate, margin ciliate, up to 6 mm long. Fronds tufted, not proliferous, fleshy. Stipe up to 13 cm, set with few scales becoming subglabrous with age, narrowly winged. Lamina 9-26 cm × 2.5-6 cm, 2-pinnate to 3-pinnatifid, narrowly oblong-lanceolate to lanceolate in outline. Pinnae glabrous, divided into linear-spathulate lobes, with the costa winged. Rhachis winged. Sori bulbous, oblong to circular, terminal on the apex of the ultimate lobes, each lobe carries a single sorus, indusium entire.
Notes: Confusion with A. rutifolium; A. theciferum has sori born on the tips of the ultimate lobes, a narrowly winged stipe and a thinner rhizome.
