Eucalyptus umbra

Eucalyptus umbra, known as the Broad-leaved white mahogany, is a common eucalyptus tree of the high rainfall coastal areas of New South Wales and adjacent areas in south eastern Queensland. The bark is rough, resembling a stringybark, though not as coarse, and in flat strips. Thick, fibrous bark, greyish brown in colour. A small or medium-sized tree, up to 25 metres tall. Sometimes a shrub in the poorer skeletal soils.

This tree occurs in dry sclerophyll forest or woodland, usually on poor shallow dry soils; north from Port Jackson. The type was collected from near Mosman, New South Wales.
