	Callistopteris Baueriana ''Callistopteris bauerianum'', known as the large filmy fern and Bauer's bristle fern, is a fern in the family Hymenophyllaceae. The specific epithet honours the Austrian botanical artist, Frederick Lucas Bauer (1760–1826), who collected plants on Norfolk Island in 1804–1805. Description The plant is a terrestrial or lithophytic fern. It has a short, erect rhizome, supported by coarse roots, with dark brown, filiform scales. Its tripinnate fronds combine a 5–25 cm tall stipe with a lanceolate lamina 10–30 cm long. Distribution and habitat The fern is endemic to Australia's subtropical Lord Howe and Norfolk Islands in the Tasman Sea The Tasman Sea (Māori: ''Te Tai-o-Rēhua'', ) is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand.

	Hymenophyllaceae The Hymenophyllaceae, the filmy ferns and bristle ferns, are a family of two to nine genera (depending on classification system) and about 650 known species of ferns, with a subcosmopolitan distribution, but generally restricted to very damp places or to locations where they are wetted by spray from waterfalls or springs. A recent fossil find shows that ferns of Hymenophyllaceae have existed since at least the Upper Triassic. Description They often appear as very dark green or even black clumps and may be mistaken for a robust moss or liverwort. The rhizome is usually thin and wiry and the fronds variously pinnate with a single strand ("nerve") of vascular tissue. As in most ferns, young fronds have circinate vernation. In most species, the frond, apart from the vascular tissue, is only a single cell thick, and they do not have any stomata. The cuticle is also greatly reduced or absent, leaving filmy ferns very susceptible to desiccation where a reliable water supply is not ...
