Vachellia valida (Tindale & Kodela) Kodela

Tree or occasionally shrub to 12 m high; branches often pendulous. Bark ±corky, often deeply fissured. Ultimate branchlets smooth, tomentose to velvety with long and short hairs (similar indumentum on leaf axes), becoming corky, furrowed, glabrous. Stipular spines 1.5–2 mm long, usually inconspicuous, often longer and curved on young plants and branchlets. Leaves: petiole 0.3–1.7 cm long, mostly with conspicuous pubescent gland at base of, or slightly below, lowest pair of pinnae; rachis (3.3–) 6.3–24.5 (–30.5) cm long, with gland (sometimes twinned) at base of uppermost 1–3 pairs of pinnae; pinnae (6–) 10–45 pairs (often subopposite), (0.7–) 1.5–4.2 (–6) cm long; pinnules 11–33 (–43) pairs, narrowly oblong or ±lanceolate, (1.5–) 1.8–5 (–6.3) mm long, (0.5–) 0.7–1.2 (–1.7) mm wide, obtuse to broadly rounded at apex, ciliate, with midvein and lateral veins usually visible. Inflorescences 1 (–5) in axils, simple or on a short axis or an extending raceme-like leafy shoot; peduncles (5–) 16–55 mm long, with involucel of bracts ⅓–½ (–⅔) way above base; heads globular, 14–27-flowered, pale yellow or creamy white, scented. Pods straight-sided or slightly constricted between seeds, ±flat or slightly convex over seeds, 4.5–25.5 cm long, 14–31.5 mm wide, woody, smooth with oblique to longitudinal veins forming a repeated ‘V’ pattern, glabrescent.

Grows in eucalypt woodland with grassy understorey or sometimes in open forest or grassland, often associated with Acacia tumida, A. platycarpa, A. holosericea s. lat. and/or A. hemignosta, in flat country, often near watercourses, in lateritic soil, red sand, sandy loams or clay loams, recorded on limestone and basalt/volcanics.

The leaves and pods are relished by cattle, fide R.J. Petheram & B. Kok, Plants of the Kimberley Region of Western Australia 357 (1983).

Can be grown by seedlings. Seeds needs soaking.
