Derivation: quornensis—refers to type locality, hills near Quorn, Flinders Ranges.

Synonymy: Not Applicable

Common name: Quorn wattle

Erect, glaucous, spreading bushy shrubs 2-3 m high; branchlets slightly angled but soon becoming almost terete; bark thin, greyish on mature stems and trunk.

Phyllodes lanceolate, 2-5 cm long, 4-8 mm broad, straight or slightly curved, flat, glabrous, glaucous to pale green, mid-vein prominent slightly eccentric, lateral veins numerous rather obscure, margins vein-like pale yellow, apex acuminate, straight or uncinate; glands small on upper margin near the base.

Inflorescences in axillary racemes shorter than the phyllodes or forming small leafy panicles longer than the phyllodes towards the ends of the branches; flower-heads globular, yellow, 8-15-flowered; peduncles slender, glabrous, c. 8 mm long; flowers 5-merous.

Legumes narrowly oblong, 5-12 cm long, 8-10 mm broad, flat but raised over the seeds, glaucous to light brown, margins thickened and slightly constricted between the seeds, apex obtuse or acute. Seeds longitudinal in legume, ovoid; funicle slender encircling the seed in a double fold and swollen into a small aril.

Distribution:  Endemic to S.Aust., with only a minor occurrence in the Flinders Ranges region around Quorn. In low woodland vegetation associated with Callitris columellaris along rocky creeks or on to the lower slopes of the ranges. Soils; shallow calcareous loamy. Rainfall 300 mm.

S.Aust.: FR, EP.

Conservation status: Lang & Kraehenbuehl (1987) consider this species to be Rare, and Leigh & Briggs (1988) consider it Vulnerable.

Related taxa: Allied to Acacia wattsiana (sp. 50) but this species differs in more flowers per head and narrow obovate phyllodes with an obtuse apex. Acacia retinodes var. uncifolia (sp. 48) is a closely allied species which differs in its acutely angular branches and more flowers per head and does not occur in the Flinders Ranges.

Cultivation: A useful bushy shrub for the lower rainfall areas and for low shelter belt planting.
