Description
Shrub 3 m high with long arching branches. Branchlets terete, commonly glandular-puberulous. Stipules persistent, setaceous, united basally, 2–5 mm long, upcurved. Phyllodes ascending to erect, inequilaterally oblong-oblanceolate, with upper margin conspicuously rounded between apex and gland, (3–) 4–6 mm long, 1.5–2 mm wide, l: w = 2–3, with mucronate-pungent apex, coriaceous, ±puberulous, with 2–4 distant slightly raised nerves and occasional anastomoses; gland about middle of adaxial margin. Inflorescences simple, 1 per axil; peduncles 5–10 mm long, puberulous with many hairs gland-tipped; heads obloid, ±5.5 mm diam., 41-flowered; bracteoles long-exserted in buds, spathulate. Flowers 5-merous; sepals 1/2‑united. Pods narrowly oblong, with one or both margins crenate, curved, to 5.5 cm long, 5–10 mm wide, crustaceous, obliquely reticulate, densely glandular-puberulous. Seeds (immature) oblique, black, shiny; aril small, apical.
Habitat
Collected from sandstone plateau.
Notes
A member of the ‘A. deltoidea’ group. Nearest to A. froggattii which has globular heads and non-crenate pods with longitudinal seeds; also related to A. deltoidea subsp. deltoidea which has larger phyllodes of different shape, non-exserted bracteoles, globular heads and non-crenate pods. Acacia obtriangularis is also related but easily distinguished by its short-cylindrical spikes.
