Eucalyptus crebra, commonly known as the narrow-leaved ironbark, narrow-leaved red ironbark or simply ironbark,[3] and as muggago in the indigenous Dharawal language,[4] is a species of small to medium-sized tree endemic to eastern Australia. It has hard, rough "ironbark" from its trunk to small branches, linear to lance-shaped adult leaves, flower buds in groups of seven, nine or eleven, white flowers and cup-shaped, barrel-shaped or hemispherical fruit. A variable species, it grows in woodland and forest from the Cape York Peninsula to near Sydney. It is an important source of nectar in the honey industry and its hard, strong timber is used in construction.
