London J. Bot. 1: 332 (1842) APNI

Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Diffuse shrub, prostrate or erect, to 1 m high; branchlets usually hairy. Phyllodes patent to inclined, more or less sessile, asymmetric, shape variable, usually a pronounced rounded or triangular gland-angle on adaxial margin near or below middle, 0.4–1.5 cm long, 1.5–4 mm wide, usually 1.5–5 times as long as wide, rigid, glabrous or hairy, green, acuminate, pungent; midrib prominent and central or near lower margin; stipules persistent. Peduncles normally 1 per axil, normally 4–10 mm long, glabrous or hairy, basal bracts 3; heads globular, 20–30-flowered, cream to pale yellow, bracteoles acuminate. Flowers 5-merous; sepals united; petals often prominently 1-veined. Pods to 4 cm long, 4–5 mm wide, firmly chartaceous to thinly coriaceous, glabrous or sometimes hairy, dark brown to blackish; seeds longitudinal to oblique, widely elliptic to spherical, c. 3 mm long, variably mottled, without aril, funicle filiform. Flowers Jun.–Oct.

Phyllode shape is very variable, ranging from semi-trullate, lanceolate or broadly to narrowly triangular but the usually prominent gland-angle on the adaxial margin distinguishes A. gunnii from other species allied to A. ulicifolia. Occasional plants with narrow phyllodes and a reduced gland-angle (e.g. north of Maffra) may be confused with A. ulicifolia or A. brownii, both of which always have glabrous phyllodes, longer (10-20 mm) peduncles and sepals only united at base (fruiting specimens collected from the Mt Johnson-Mt Victoria area in East Gippsland are possibly of hybrid origin).
