About Acacia crassicarpa A.Cunn. ex Benth.
Acacia crassicarpa A.Cunn. ex Benth. is a tree that typically reaches 6–25 meters (20–82 feet) in height. It has bark that is heavily fissured with numerous chinks, cracks, and crevices. Its branchlets are hairless (glabrous) and slightly angular near their tips. The species has leathery or thinly leathery phyllodes, shaped lanceolate to sickle-shaped, that measure 80–270 mm (3.1–10.6 in) in length and 10–45 mm (0.39–1.77 in) in width. Its phyllodes have many parallel veins, with three veins that are more prominent than the others. Pale yellow to light golden yellow flowers are produced in spikes 30–70 mm (1.2–2.8 in) long. Flowering takes place between May and September. The seed pods are flat, oblong to narrowly oblong, 40–120 mm (1.6–4.7 in) long and 20–45 mm (0.79–1.77 in) wide when including the wing. The pods are more or less straight, and sometimes become spirally twisted. The seeds are oblong to egg-shaped, black, 5–6 mm (0.20–0.24 in) long, with an aril 5–20 mm (0.20–0.79 in) long. This tree, commonly called thick-podded salwood, grows in woodlands and open forest on sandy or rocky soils. In Australia, it is found in tropical Queensland, from the Torres Strait islands south as far as Townsville, with isolated disjunct populations on Whitsunday Island and near Mackay. It also occurs in Irian Jaya and Papua New Guinea.
