Acacia clandullensis B.J.Conn & Tame, Austral. Syst. Bot . 9: 849 (1996)
Open, pendulous shrub to 1 (–2) m high; stem unbranched at base or with few primary downwards arching branches. Branchlets slightly ribbed, becoming terete, green to brown, smooth, densely hairy. Phyllodes somewhat crowded; base of lamina coplanar with branchlets, with lamina towards apex twisted and/or sometimes bent, asymmetric, orbicular to broadly elliptic to obovate, (4–) 7– 11 (–16) mm long, (3–) 5–10 (–11) mm wide, l:w = 1.2–1.4 (–1.6), base oblique and asymmetric, usually acute, margin thickened, markedly undulate and with scattered hairs, apex oblique, acute-acuminate to acute or obtuse mucronate, subglossy, light green; gland inserted to 1 mm above pulvinus, small, with inconspicuous rim. Inflorescences with peduncles (5–) 8–9 (–11) mm long, about as long as floral phyllodes, moderately hairy; heads 4–5 mm diam., 20–26 (–30)-flowered, pale yellow or sometimes yellow to bright.< /FONT > Corolla lobes usually with few long hairs. Pods oblong, flat, straight or slightly curved, 60–75 mm long, 15–22 mm wide, firmly coriaceous, dull, dark brown; margin prominent, barely constricted between seeds, slightly undulate.
Mostly confined to the Clandulla and Glen Davis areas of N.S.W., with a localised population near Yerranderie. Occurs mostly on stony sandy or loamy clay soils, frequently in Eucalyptus rossii woodlands, at higher altitudes.
Branchlet hairs short and subappressed with longer patent hairs, 0.2–0.8 mm long, grey to whitish. Inflorescence hairs similar to branchlets hairs. The young phyllodes with few scattered long hairs on the lamina becoming distally glabrous.
This species is a member of the " A. uncinata group" and has some similarity to A. sertiformis but differs in its lower diffuse habit, very small twisted bright green phyllodes and fewer pale yellow flowers per head. It is also distinguished by the appressed to subappressed hairs on the branchlets, pulvini and peduncles and the closely appressed appearance of the young phyllodes against the branchlet. The glossy appearance of the phyllodes appears to be owing to the lack of a fibrous-like cuticular ‘wax’ which is present on the phyllodes of all other members of the group. It is a distinctive taxon in the field with its small lemon-yellow flowers, open, downwards arching branches and the often very small phyllodes appearing to be appressed to the branchlets.
