Acacia brachystachya
species of plant
Acacia brachystachya commonly known as umbrella mulga, umbrella wattle, turpentine mulga, grey mulga or false bowgada, is a species of flowering plant in the family Fabaceae and is endemic to Australia. It is a erect or spreading, bushy shrub or tree with grey bark, straight linear or slightly curved phyllodes, cylindrical heads of bright yellow flowers, and straight pods. It is native to all mainland Australian states except Victoria, and also occurs in the Northern Territory.
Description
Acacia brachystachya grows as an erect or spreading bushy shrub or tree 2–6 m (6 ft 7 in – 19 ft 8 in) high and 5 m (16 ft) wide and grey, smooth or fissured bark. The phyllodes are rigid, linear or slightly curved, 40–160 mm (1.6–6.3 in) long and 1–3 mm (0.039–0.118 in) wide and more or less glaucous with many closely spaced veins, and hairs pressed against the surface. The flowers are bright yellow and borne in one or two cylindrical heads 13–20 mm (0.51–0.79 in) long, in axils on a peduncle 2–8 mm (0.079–0.315 in) long. Flowering usually occurs from
April to August, depending on weather conditions, and the pods are more or less straight, slightly flattened, 20–80 mm (0.79–3.15 in) long, 4–8 mm (0.16–0.31 in) wide and sticky, containing seeds 5–8 mm (0.20–0.31 in) long and 3–5 mm (0.12–0.20 in) wide with a thread-like aril.
Taxonomy
Acacia brachystachya was first formally described in 1864 by George Bentham in his Flora Australiensis from specimens collected on the "Mutanie Ranges" in New South Wales during the Bourke and Wills expedition. The specific epithet (brachystachys) means 'a short ear of corn', referring to the relatively short flower spikes.
Distribution and habitat
Acacia brachystachya is found in all continental Australian states except Victoria, and also in the Northern Territory.

Why this record matters
“Acacia brachystachya” is worth following because a concise public description often conceals a longer documentary argument. Here, Acacia, brachystachya and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 26, 2025. The linked authority identifier is Q2715257. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1864.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
