Eucalyptus crebra
Eucalyptus crebra, commonly known as the narrow-leaved ironbark (also called narrow-leaved red ironbark or simply ironbark, and known as muggago in the Dharawal language), is a small to medium tree native to eastern Australia. It can grow up to about 35 meters tall and has thick, rough, dark ironbark from the trunk to the branches. Young trees have linear to lance-shaped leaves; adults have long, narrow leaves that are dull green on both sides.
The tree’s flower buds appear in groups of seven, nine or eleven on branched inflorescences, and the flowers are white. The fruit is a woody cup-shaped to barrel-shaped capsule. Eucalyptus crebra forms a lignotuber, helping it to regrow after fire.
Habitat and range: It grows in sandy soils in woodlands and forests from the Cape York Peninsula down to near Sydney, New South Wales, and Queensland.
Uses: The timber is hard and strong, used for sleepers and construction. The tree is also an important nectar source for honey production, giving light-colored, delicately flavored honey. It is used as a shade tree, for roadside planting, and is available as a cultivar.
Taxonomy and status: Eucalyptus crebra was described by Ferdinand von Mueller in 1859. It is listed as Least Concern by the IUCN.
