About
Jagera pseudorhus, commonly known as foambark or fern-leaved tamarind, is a species of plant in the lychee family Sapindaceae, native to New Guinea and the northern half of eastern Australia. It is known for the foam that appears on the trunk after heavy rain.
Where it grows
In Australia, the native range is along the eastern seaboard from Myall Lakes, New South Wales, north to the tip of Cape York Peninsula, Queensland. In New Guinea they occur in the portion of the island nearest Cape York. They occur in drier rainforest types such as monsoon forest, gallery forest and beach forest, at altitudes from sea level to 850 m (2,790 ft).
Uses
Indigenous Australians use foam from crushed bark or leaves as a fish poison. It was also used as a soap in New Guinea. The timber has been used to make tool handles, and honey is harvested from the tree.
