Acacia colletioides
species of plant
Acacia colletioides, commonly known as wait-a-while, pin bush or spinebush, is a species of flowering plant in the family Fabaceae and is endemic to southern continental Australia. It is a rigid shrub or tree with sessile, straight to more or less curved and terete phyllodes, more or less spherical heads of bright yellow flowers, and linear, thinly leathery pods.
Description
Acacia colletioides is a shrub or tree that typically grows to a height of 0.5–3 m (1 ft 8 in – 9 ft 10 in) and has mostly glabrous branchlets with scars where phyllodes have fallen. The phyllodes are sessile and inserted on distinct, yellow stem-projections. The phyllodes are straight to more or less curved, more or less terete, usually 15–30 mm (0.59–1.18 in) long and 1.0–1.5 mm (0.039–0.059 in) wide tapered and sharply pointed. The flowers are borne in two, more or less spherical or widely elliptic heads 3–5 mm (0.12–0.20 in) long and 3–4.5 mm (0.12–0.18 in) in diameter in axils on peduncles 1.5–5 mm (0.059–0.197 in) long. Each head has 12 to 24 bright yellow flowers. Flowering occurs from July to November and the pods are linear, constricted between the seeds, up to 70 mm (2.8 in) long and 3–5 mm (0.12–0.20 in) wide, thinly leathery and glabrous. The seeds are oval to egg-shaped, black, shiny and 3.5–4.0 mm (0.14–0.16 in) long with an orange or yellow aril nearly surrounding the seed.
Taxonomy
Acacia colletioides was first formally described in 1842 by the botanist George Bentham in Hooker's London Journal of Botany from specimens collected by Allan Cunnigham on the "Harrington Plains" in the "interior of New South Wales".
The public source identifies “Acacia colletioides” as species of plant. This brief keeps that definition visible, then builds a research path around Acacia, colletioides and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Acacia colletioides”, 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 Sep 23, 2026. The linked authority identifier is Q9563468. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1842.
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.
