Lomaria nuda, commonly known as the fishbone waterfern, is a fern that grows up to a metre tall, and is abundant in rainforest and eucalyptus forests in eastern Australia.

[3] The mature fishbone waterfern typically has simple, pinnate fronds of length 40–60 cm.

The longest pinna of the sterile ferns are in the middle of the frond, with length decreasing towards each end.

Aside from this main difference, the fishbone waterfern shows a typical sexual reproductive process to most ferns.

Thus this fern will often be found growing in roadside ditches where sun is plentiful, but water pools after running off roads.

Creek beds are a similar, naturally occurring high water low rainfall habitat.

Both forest types tend to be high rainfall, with a large percentage of canopy cover to ensure shade.
