Species of plant

Acacia brachystachya (bra chy stà chy a pronounced 'brackeeSTAKEeea'), turpentine mulga or false bowgada, is a shrub in the family Fabaceae. The species occurs in mulga and heath communities on sandhills and rocky ridges in all mainland states of Australia, except Victoria. Like most Acacia species, it has phyllodes rather than true leaves. These may be up to 18 centimetres long, are mostly one to three millimetres wide and a grey green colour. The flowers are yellow, and held in cylindrical clusters about two centimetres long (up to 25 millimetres). and came from Ferdinand von Mueller's herbarium. This species is of the Acacia genus with the specific species name being brachystachya. The plant is called brachystachya due to its short spikes, brachys (short), and stachys (spike). Acacia brachystachya is classed as a group 1 Acacia under the informal groupings outlined by D. A Morrison and S. J Davies. Group 1 plants are identified as having phyllodes, as well as being the only group which features flowers in cylindrical heads.

Acacia Mill. sect. Juliflorae Benth., commonly referred to as mulga includes A. brachystachya. Most Acacias have been studied comprehensively, however many mulgas have not. It has been concluded that it is likely that mulga plants are insect pollinated as this is often the case with arid zone Acacias. Although it generally flowers in April–August, A. brachystachya does flower irregularly depending on weather and climatic conditions. These flowers are hermaphroditic and grow after heavy rainfall at any time of year. Despite the potential year round flowering, reproduction does not always follow. Mature pods are usually only developed when summer rain is the cause of flowering followed by rain in the subsequent winter. Because A. brachystachya is most easily distinguished from similar species by assessing the pods, it can be difficult to correctly identify without having experiencing the appropriate climatic conditions.
