Endiandra globosa is a medium sized Australian rainforest tree. Despite the common name of Black Walnut, this tree is unrelated to northern hemisphere walnuts, and is a Laurel.
The Black Walnut is restricted to riverine rainforest. Growing on rich alluvial soils and on moist slopes in subtropical rainforest; in the Brunswick and Tweed valleys in New South Wales and adjacent areas in Queensland. Another population grows from Ingham to Cairns in tropical Queensland.[1]
The Black Walnut is considered rare, with a ROTAP rating of 2RC-. Several signposted specimens can be seen on the roads around the town of Murwillumbah in north eastern NSW.
The unbuttressed trunk is of whitish, grey or brown bark. A mature tree grows to around to 25 metres tall.
Leaves are broad-elliptic to elliptic or ovate, veiny and usually 7–15 cm long, 3–6 cm wide, veins often yellowish. The horizontal form of the branches and attractive dark foliage makes this a particularly beautiful tree.
Creamy white flowers form between October and January. The fruit matures in autumn and is often the size of a tennis ball. The black, fleshy drupe contains a large woody seed, which itself has attractive veiny patterns. Germination is fairly slow but reliable. Roots and shoots appear around November.
