Description

Shrub to c. 2 m high. Branchlets sparsely hirsutellous, slightly resinous. Phyllodes crowded or subcrowded, sometimes a few subverticillate or subfasciculate, ascending to erect, slender, ±straight, 10–22 (–28) mm long, 0.6–1 mm wide, terete to subterete or occasionally ±slightly compressed, nerves not evident but normally with some longitudinal furrows, obliquely and excentrically mucronate or rostellate, often subuncinate or sometimes uncinate, sparsely tuberculate, glabrous or occasionally sparsely hirsutellous; gland minute, obscure or absent, 5–7 mm above pulvinus. Inflorescences simple, 1 per node; peduncles 6–10 mm long, normally glabrous, ebracteate at base; heads globular, (20–) 25–35-flowered, golden, slightly resinous. Flowers 5‑merous; sepals c. 1/2–2/3-united. Pods linear, straight-edged or constricted between seeds, to c. 4 cm long, 4 mm wide, firmly chartaceous, brown, glabrous, slightly resinous.

Notes

Acacia barakulensis was noted by B.R.Maslin, Fl. Australia 11A: 459 (2001) under A. johnsonii. It is a member of the ‘A. johnsonii group’ very closely related to the more widespread A. burbidgeae which is distinguished by its shorter peduncles and generally longer, more obviously incurved phyllodes with the lower margin broader than the upper (narrow phyllodes therefore appearing ±triquetrous in section when dry).
