Endiandra floydii

Endiandra floydii is a small-sized rainforest tree. Despite its common name, Crystal Creek walnut, this tree is unrelated to northern-hemisphere walnuts, and is a laurel. It is named after the Australian botanist, Alexander Floyd.

Habitat
The Crystal Creek walnut is restricted to paleozoic metamorphics but with overlying basalt soils in the Mount Warning area of New South Wales, and a couple of adjacent areas in Queensland. The Crystal Creek walnut grows in rainforest and is also found as an understorey plant in brush box ecotone areas, on moderately steep slopes no higher than 430 metres above sea level.

The Crystal Creek walnut is considered endangered, with a ROTAP rating of 2E.
