Eucalyptus copulans is a small eucalyptus tree, up to 10 metres tall. Previously considered extinct. Two specimens are known at Wentworth Falls in the Blue Mountains region of Australia.
Horticulturists at Mount Annan Botanic Gardens are attempting to avoid the extinction of this species by the propagation of seedlings, and replanting them in their former habitat.
