Source-derived summary

Acacia macdonnelliensis, commonly known as the MacDonnell mulga or the Hill mulga, is a species of Acacia native to central Australia. The Indigenous Australians the Alyawarr peoples know the plant as irrar, the Kaytetye know it as arleth-arlethe or arwele arleth-arlethe and the Western Arrernte peoples know it as irrkwarteke.

Taxonomy

There are two subspecies:

Acacia macdonnelliensis subsp. macdonnelliensis Maconochie

Acacia macdonnelliensis subsp. teretifolia Maslin

Description

This bushy shrub or tree typically grows 3 to 6 metres (10 to 20 ft) tall and has deeply fissured grey bark. It has sparsely hoary to glabrous branchlets with obscure, resinous ridges. It has erect, glabrous to hoary, grey-green phyllodes with a narrow elliptic to linear shape that are 4 to 15 centimetres (2 to 6 in) in length and 0.8 to 5 millimetres (0.031 to 0.197 in) wide. It produces yellow flowers in July. The dense golden flower spikes are 0.6 to 3 cm (0.24 to 1.18 in) in length and have a width of 3 to 6 mm (0.118 to 0.236 in). After flowering linear pale brown seed pods form that are constricted between each seed.

Editorial summary

“Acacia macdonnelliensis” enters the record as species of plant. Crown Archives preserves that source wording while asking what Acacia, macdonnelliensis and species can confirm, complicate or overturn.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 185-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Acacia, macdonnelliensis and species.
Editorial analysis

Why this record matters

“Acacia macdonnelliensis” is worth following because a concise public description often conceals a longer documentary argument. Here, Acacia, macdonnelliensis and species provides the most credible route into that argument.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 18, 2026. The linked authority identifier is Q15287722. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
