About Acacia leichhardtii Benth.
Acacia leichhardtii Benth. is a shrub that typically reaches a height of 3 metres (10 ft) with a spreading growth habit. It produces slender branches that usually arch downward, and its branchlets are covered in soft hairs. This species has small grey-green phyllodes that range from standing out from the stem to bending back toward it; the phyllodes have a narrowly oblong-elliptic to lanceolate shape. The hairless phyllodes are mostly straight to shallowly incurved, measuring 1.5 to 3 cm (0.59 to 1.18 in) in length and 3 to 6 mm (0.12 to 0.24 in) in width. They are abruptly contracted at the base and have a prominent midrib. Simple, sweet-scented inflorescences grow in bunches of 12 to 20, bearing spherical flower-heads that hold 20 to 40 bright golden flowers. After flowering, hairy seed pods develop; these pods are narrowly oblong, ranging from curved to straight, reaching up to 10 cm (3.9 in) in length and around 9 mm (0.35 in) in width. The black seeds inside the pods are oblong to elliptic, and measure 5 to 6 mm (0.20 to 0.24 in) in length. This species is native to Queensland, Australia, where it occurs from the Central Highlands Region on the Blackdown Tablelands in the north, southward to around Toowoomba in the southeast on the Darling Downs. It grows on sandstone ranges in shallow stony sandy soils, as a component of open Eucalyptus woodland communities.
