Acacia homalophylla is a small tree found in the eastern half of Australia, where it is known as the yarran.

[2] Acacia homalophylla has a clean trunk and leafy head, a dark gray, rough bark, narrow, usually straight leaves, and yellow flowers in balls.

The evergreen, grey-green phyllodes have a narrowly elliptic or oblanceolate or more or less linear shape and are straight to slightly curved with a length of 4 to 11 cm (1.6 to 4.3 in) and a width of 4 to 7 mm (0.16 to 0.28 in).

Following flowering firmly papery to thin leathery seed pods form that are straight and flat with a length of up to 7 cm (2.8 in) and a width of 3 to 7 mm (0.12 to 0.28 in).

In New South Wales it is found to the west of Muswellbrook and Emmaville and is often a part of Casuarina cristata, rosewood and box communities growing in brown earthy soils.
