Dennstaedtia davallioides

Dennstaedtia davallioides, commonly known as the lacy ground fern, is a species of fern native to eastern Australia, from the Bunya Mountains in central Queensland south through eastern New South Wales, and into Victoria southwest to the Otway Ranges.

Plants can be attacked by green caterpillars in cultivation....read more on Wikipedia.
