Acacia calantha is a species of flowering plant in the family Fabaceae and is endemic to Queensland, Australia. It is a glabrous, moderately dense shrub with thread-like phyllodes, spherical heads of bright golden yellow flowers and narrowly oblong pods.
Acacia calantha is a glabrous, moderately dense, slightly sticky shrub that typically grows to a height of 1 to 3 metres (3 to 10ft) and has slender, yellowish brown to grey branchlets. The phyllodes are thread-like, slightly bent, 70–150mm (2.8–5.9in) long and about 1mm (0.039in) wide. The flowers are borne in a spherical head in leaf axils on a peduncle3–6mm (0.12–0.24in) long, each head with about 36 bright golden yellow flowers. Flowering has been observed from July to September and in December, and the pods are firmly papery to very thinly leathery, narrowly oblong, up to 60mm (2.4in) long anf 5–6mm (0.20–0.24in) wide. The seeds are dark brown to black, oblong to elliptic, 3–4mm (0.12–0.16in) long with a cream-coloured aril.[2][3][4][5]
