Persoonia acerosa

Erect to spreading shrub, young branchlets glabrous to sparsely hairy.

Leaves subterete and prominently channelled above, 1.2–2.3 cm long, c. 0.5 mm wide, strongly incurved, smooth, sparsely hairy when young, soon glabrescent.

Inflorescences growing on into a leafy shoot; flowers mostly subtended by full-sized leaves; pedicels 1–2 mm long, spreading to suberect, glabrous or sparsely hairy. Tepals 8–10 mm long, glabrous. Ovary glabrous.

It is typically found in the Blue Mountains, but extends south to Hill Top. It would be great to know if it is still in Hill Top. It has distinctly lime-green foliage.
