| Eucalyptus crebra | |
Eucalyptus crebra, commonly known as the Narrow-leaved ironbark or Narrowleaf red ironbark, is a type of Ironbark tree native to eastern Australia. A member of the large genus Eucalyptus, this tree is in the Myrtaceae family and can grow to a large spreading tree up to 35 m (100 ft) high. It is an important source of nectar in the honey industry and its hard, strong timber is used in construction.
Taxonomy
The Narrow-leaved ironbark was originally described by Victoria state botanist Ferdinand von Mueller in 1859.[1] The specific epithet is the Latin adjective crebra "crowded" or "close together".[2] Within the genus Eucalyptus, it belongs in the subgenus Symphyomyrtus.
Description
This plant is a large spreading tree, which may reach 35 m (100 ft) in height. The rough furrowed bark is grey mottled with yellow and orange. The narrow lanceolate leaves are a uniform greyish-green in colour and measure 7–15 cm (2.8-6 in) in length by 0.9–1.7 cm (0.4-0.6 in) wide. The small white flowers appear from late autumn to spring, and are followed by small pods.[3]
Distribution and habitat
The Narrow-leaved ironbark is found in eastern Australia, from Picton southwest of Sydney north through New South Wales and Queensland to the vicinity of Cairns.[2] It grows on sandier soils.[4]
Ecology
Koalas can consume the leaves, and the flowers are pollinated mainly by insects. The southern or shady side of the trunk is habitat for lichens.
Uses
The tree has a hard, strong, and dark red timber, which has been used for sleepers and construction.[2] A plank has been recorded as being used for Elizabeth Farm, Australia's oldest surviving European dwelling.[5] It is used as a shade tree or to line roadways, and is also available as a cultivar. It is useful in honey production as the flowers are heavy in nectar and pollen;[2] the resulting honey produced by bees is light-coloured and delicately flavoured. [6]
