Status: Native
Rhizome short, suberect or creeping; rhizome scales dark brown. Fronds tufted, herbaceous, arching. Stipe up to 20 cm long, dark brown to black, shiny, glabrous. Lamina pinnate, linear to lanceolate in outline; 36 × 11 cm, excluding a glabrous extension of the rhachis of varying length, which often ends in a proliferous bud or lamina with a terminal pinna. Rhachis, petiole and pinnae glabrous. Pinnae numerous (up to 15 pairs), persistent, lunulate, petiolate, alternate; 25-50 × 13-25 mm, reduced in size towards the apex, the midrib forms the lower margin, outer margin irregurly incised into broad lobes. Sori elongate on apices of the pinna lobes, indusial flap linear to shallowly lunate, glabrous.
Notes: Resembles A. incisum which has a less wider lamina, more pinnae (up to 40 pairs) that are pilose and have a short petiole. A. mendoncae has smaller pinnae with serrate margins. A. soboliferum has a winged stipe and rhachis
Derivation of specific name: lunulatum: moon-shaped; referring to the half-moon shape of the pinnae.
