Fertile lobes have the sori continuous, linear and exindusiate (without an indusium) but protected by reflexed leaf margins.

Pinnae are pale greyish-green, almost a glaucous colour, they are paired and opposite and set at a wide angle and very lobed.

[4] This fern is a ‘weedy’ opportunistic species, freely colonising disturbed sites on the margins of, or within, wet forest,[4] and often forming extensive colonies.

Bat's wing fern is commonly found growing on the margins of wet forests, along more open scrubby creeks and gullies and at the base of cliffs.

[5] The bat's wing fern is found in many Tasmanian nurseries and is popular as both an indoor or outdoor plant, as it requires little sunlight and is very aesthetically pleasing.
