Acacia yirrkallensis

The smooth, brown/dark red-brown/yellowish branchlets are angular and have ridges which have minute resin crenulations.

The straight to slightly curved, leathery phyllodes are very narrowly elliptic, and 1.5–4.5 cm by 1.4–5.2 mm, and have prominent stomata, with 1 or more prominent veins and indistinct parallel minor veins.

The woody, straight-sided, flat pods are oblanceolate, narrowing toward the base and 2–5 cm by 4–9 mm, and have oblique striations.

The stalk of the ovule expands to give a top-shaped aril.

[1] It usually grows in eucalypt forest and woodland on grey sandy podsols, on laterite and bauxite on stony sandstone ridges and gorges.
