Road-leaved Hickory, Hickory Wattle, Mountain Hickory, Large-leaf Wattle, Tanning Wattle, Black Wattle

Family: Fabaceae subfamily Mimosoideae

Acacia falciformis grows to 10 m high and has an erect or spreading habit. It grows down the east coast of Australia in coastal areas and extending over the Great Dividing Range to the western slopes in a variety of habitats including moist rocky slopes, gullies and along watercourses. It also grows in Victoria and Qld.

The phyllodes are usually oblanceolate or oblong-oblanceolate or narrowly elliptic, straight to falcate, to 22 cm long, and 4 cm wide, glabrous and mostly green to blue-green.

Flowers are arranged in globular heads, with diameter to 6 mm, containing up to 25 pale yellow/bright yellow to cream-coloured, very small staminate flowers, occurring in July to October. The globular heads are arranged into racemes in leaf axils with up to about 20 heads per raceme.

The flat, leathery, brown seed pods are more or less straight but can be slightly curved, to 13 cm in length and to 2.5 cm wide and contain shiny, black seeds.
