Acacia siculiformis
species of plant
Acacia siculiformis, commonly known as dagger wattle or creek wattle, is a species of flowering plant in the family Fabaceae and is endemic to the south-east of Australia. It is a glabrous shrub with rigid, sharply pointed, lance-shaped to linear or narrowly elliptic phyllodes, spherical heads of pale yellow flowers and oblong to narrowly oblong, papery pods.
Description
Acacia siculiformis is a glabrous shrub that typically grows to a height of 2–3 m (6 ft 6.7 in – 9 ft 10.1 in) but is sometimes procumbent. Its phyllodes are sessile, rigid, sharply pointed, lance-shaped to linear or narrowly elliptic, 10–35 mm (0.39–1.38 in) long and 1.5–4 mm (0.059–0.157 in) wide. There are stipules about 0.5 mm (0.020 in) long at the base of the phyllodes. The phyllodes are normally slightly asymmetric and have a prominent midrib. The flowers are usually borne in a single spherical head in axils on a peduncle up to 13 mm (0.51 in) long, each head 4.5–7 mm (0.18–0.28 in) in diameter with 30 to 40 pale yellow flowers. Flowering occurs from August to November and the pods are oblong to narrowly oblong and papery, up to 55 mm (2.2 in) long and 4–7 mm (0.16–0.28 in) wide. The seeds are oblong to elliptic, 3.0–3.5 mm (0.12–0.14 in) long and dark greyish brown to black.
Taxonomy
Acacia siculiformis was first formally described in 1842 by George Bentham in the London Journal of Botany from an unpublished description by Allan Cunningham of specimens he had collected.
This brief starts where responsible research should: with the source description of “Acacia siculiformis” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Dec 30, 2025. The linked authority identifier is Q15288985. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1842.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
