Eucalyptus balladoniensis, commonly known as the Balladonia mallee, is a mallee tree that is native to Western Australia.[1]
Description
The tree typically grows to a height of 2.5 to 10 metres (8.2 to 32.8 ft) and has rough flaky bark. It blooms between August and October producing yellow white flowers.[1]
The bark is persistent throughout the length of the tree with shortly fibrous or "ironbark" texture. The bark tends to be grey or black with both pith and bark glands absent. Adult leaves are disjunct with a lanceolate to falcate shape and are basally tapered.[2] The leaves are glossy, green, thick, and concolorous with quadrangular petioles. The conflorescence is simple and axillary with seven-flowered umbellasters. The peduncles are terete or narrowly flattened or angular and about 3 millimetres (0.12 in) wide.[2] Fruits that form are hemispherical with a depressed disc and exserted valves exserted.
Taxonomy
The species was first formally described by the botanist Ian Brooker in 1976 in the work Six new taxa of Eucalyptus from Western Australia. published in the journal Nuytsia,[3] from samples collected by Brooker in 1970 between Zanthus and Balladonia.[2] There are two recognised subspecies:
- Eucalyptus balladoniensis subsp. balladoniensis
- Eucalyptus balladoniensis subsp. sedens[4]
Distribution
It is found on limestone plains and rises in southern parts of the Goldfields-Esperance region of Western Australia where it grows in calcareous sandy and loamy soils.[1]
