Burra acacia

Acacia falcata Willd. (Fabaceae), the burra, sally, or sickle wattle, is a slender erect to spreading shrub or small tree of eastern Australia, occurring from south-eastern Queensland through New South Wales on sandy and clay soils in open eucalypt forest and woodland, and growing 2–5 m tall. Stems are slender and glabrous, often slightly angular when young. Like most Australian wattles the species lacks true bipinnate leaves at maturity; the photosynthetic organs are phyllodes that are flat, sickle-shaped (falcate), oblanceolate, 7–15 cm long and 1–2.5 cm wide, with a single prominent central vein, finely reticulate lateral venation, and one small marginal gland near the base. Inflorescences are short axillary racemes of two to seven globose heads of 20–30 pale cream-yellow flowers about 5 mm across, produced from autumn to winter. Pods are linear-oblong, flat, 4–10 cm long, slightly curved, and brown at maturity.
