Wurun or Binap is a large Eucalypt which grows from 10 to 50 metres tall. It possesses rough brown bark at the base and smooth white bark further up, and has broad and long leaves. It can be differentiated from Bial by its shedding of bark during summer. It flowers from January to April with clusters of white flowers.

The Wurundjeri-woiwurrung would use the tree for its wood, which would be made into tarnuks and shields.

It grows in many soil types, but grows tallest in moist, deep loam soils in higher elevations with full sun.
