Description
The plant is a terrestrial fern. The creeping or shortly erect rhizome has dense apical scales. Its fronds are up to 70 cm long and 40 cm wide.[2]
Distribution and habitat
The fern is endemic to Australia's subtropical Lord Howe Island in the Tasman Sea. It grows in shaded mountain forest, especially on the summits of Mounts Gower and Lidgbird.[2]

gollark: See, it's important to recognize that distinction.
gollark: What do you mean you "perceive" time as discrete? You mean you *arbitrarily think so*, or what?
gollark: Quite a lot.
gollark: > The Planck time is the unique combination of the gravitational constant G, the special-relativistic constant c, and the quantum constant ħ, to produce a constant with dimension of time. Because the Planck time comes from dimensional analysis, which ignores constant factors, there is no reason to believe that exactly one unit of Planck time has any special physical significance. Rather, the Planck time represents a rough time scale at which quantum gravitational effects are likely to become important. This essentially means that while smaller units of time can exist, they are so small their effect on our existence is negligible. The nature of those effects, and the exact time scale at which they would occur, would need to be derived from an actual theory of quantum gravity.
