Acacia kempeana
species of plant
Acacia kempeana commonly known as wanderrie wattle, witchetty bush or granite wattle, is a species of flowering plant in the family Fabaceae and is endemic to a arid parts of central and western Australia. It is a spreading shrub or tree with furrowed, grey or brown bark, leathery narrowly elliptic to narrowly lance-shaped phyllodes with the narrower end towards the base, one or two dense spikes of bright golden yellow flowers and leathery, oblong to narrowly oblong pods.
Description
Acacia kempeana is spreading shrub or tree that typically grows to a height of up to 5 m (16 ft), rarely more, usually with grey or brown bark and terete, glabous branchlets. Its phyllodes are narrowly elliptic to very narrowly elliptic, sometimes narrowly lance-shaped with the narrower end towards the base, mostly 30–75 mm (1.2–3.0 in) long, 4–15 mm (0.16–0.59 in) wide and leathery with up to three veins slightly more prominent. The flowers are bright golden yellow, and densely arranged in one or two spikes in upper axils on glabrous peduncles 5–12 mm (0.20–0.47 in) long. Flowering occurs whenever temperature and soil moisture are high The pods are leathery, oblong to narrowly oblong, 20–70 mm (0.79–2.76 in) long, 1.0–1.6 mm (0.039–0.063 in) wide, glabrous and often slightly resinous.
Taxonomy
Acacia kempeana was first formally described in 1882 by Ferdinand von Mueller in the Australasian Chemist and Druggist. The specific epithet (kempeana) honours the reverend Friedrich Adolph Hermann Kempe (1844–1928), co-founder of the Hermannsburg Mission, who sent about 600 plant specimens to Ferdinand von Mueller in Melbourne, including the type of A. kempeana which he gathered in 1879.
Distribution and habitat
This species of wattle is widely distributed through arid and semi-arid areas of Western Australia, western South Australia, and the Northern Territory. It is grows in a variety of soils on stony hillsides, often in mulga woodland on red sandy loam plains.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Acacia kempeana”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 21, 2026. The linked authority identifier is Q2709193. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1882, 1844, 1928 and 1879.
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.
