Endiandra hayesii

Endiandra hayesii is an Australian rainforest tree. Despite the common name of rusty rose walnut, this tree is unrelated to northern hemisphere walnuts, and is a laurel. The former habitat is lowland sub tropical rainforest, most of which has been cleared. However some trees persist in cool sheltered gullies as far south as the Richmond River, New South Wales to just over the border at Burleigh Heads in Queensland.[1] The rusty rose walnut is considered rare, with a ROTAP rating of 3RC-. It is named after H.C. Hayes, who collected this species at Minyon Falls.
