Status: Native
Description:
Rhizome short, erect, up to 10 mm in diameter; rhizome scales brown, c. 4 mm in length. Fronds tufted, membranous to firmly herbaceous, arching. Stipe up to 8 cm long, dark brown to black, shiny, with numerous reddish brown hairs and long, linear, brown scales. Lamina pinnate, linear-lanceolate in outline;10-40 × 2-4 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 and pinnae thinly set with pale hairs. Pinnae numerous (up to 40 pairs), persistent, subrectangular, shortly petiolate or sessile, alternate; 10-22 × 6-10 mm, reduced in size towards the base and apex, the midrib forms the lower margin, outer margin irregularly incised into lobes. Sori on the undersurface of deflexed, membranous, oblong to lunate, glabrous or thinly hairy indusial flaps.
Notes: Resembles A. lunulatum and A. mendoncae which have fewer (up to 15 pairs) and glabrous pinna, a wider lamina and a longer petiole. It also may be confused with Lindsaea odorata, an unrelated species, which has glabrous, non proliferous fronds, a creeping rhizome and smells of almonds when crushed.
Derivation of specific name: incisum: cut-in; referring to the strongly incised pinna margins.
Habitat: Terrestrial or lithophyte, on seasonally moist earthbanks, in rock crevices, at boulder bases in deciduous woodland or riverine forest at medium to low altitudes.
Altitude range: (metres) 500 - 1400 m
