Muelleria 27: 209 (2009) APNI

Taxonomic status:Accepted

Occurrence status:Endemic

Establishment means:Native

Threat status:Victoria: vulnerable (v); listed in Flora and Fauna Guarantee Act 1988

Slightly aromatic shrubs or small trees, 1–6(–8) m high; branchlets ribbed, with appressed, minute hairs on ribs. Phyllodes narrowly elliptic to oblong-elliptic, sometimes oblanceolate or lanceolate, 2–4.5(–6) cm long, (3–)5–10(–13) mm wide, obtuse to subacute, mucronate to beak-shaped, sub-uncinate, resinous-punctate, normally with minute appressed hairs on margins and main veins; veins 2, lateral veins few and obscure; gland 0–1 mm above pulvinus. Peduncles 1–3(–5), (3–)5–9(–10) mm long, densely tomentose, basal bract persistent; heads globular to slightly obloid, 25–30-flowered, lemon yellow. Flowers 5-merous, sepals united. Pods linear to narrowly oblong, 3.5–8 cm long, 3–5 mm wide, firmly chartaceous to thinly coriaceous, with dense, minute appressed hairs when young; seeds longitudinal, 3.5–4.7 mm long, shiny, dark brown or black, funicle usually twice folded, aril terminal. Flowers Aug.–Oct.    

CVU, OtP, VVP. Confined to the Bacchus Marsh area (Lerderderg Gorge, Long Forest, Coimadai, Balliang and Werribee) where it occurs in low hilly areas in Eucalyptus woodland. Records from outside the Bacchus Marsh area are thought to be mislabelled or possibly of cultivated material.

Similar to A. exudans (see note under that species). Previously included in A. verniciflua, but distinguished from that species by the distinctly ribbed branchlets that have minute appressed hairs along the ribs. Forms with short phyllodes may resemble A. montana.
