Acacia burbidgeae Pedley

Common Name

Burbidge’s Wattle




Disjunct, occurring in south-eastern Qld between Cunnamulla and St George, and the Chinchilla area; a variant occurs near Rolleston; also in north-eastern N.S.W. near Emmaville.


Shrub to c. 2 (-4) m high. Branchlets sparsely to moderately puberulous to hirsutellous, rarely glabrous, slightly resinous. Phyllodes frequently subcrowded, sometimes a few subverticillate or subfasciculate, patent to erect, slender, shallowly incurved, sometimes straight, normally subterete but drying ±triquetrous in section or ±flat and with a discernible longitudinal groove on each face, (15–) 20–45 mm long, 0.5–1 mm wide, with lower edge or margin broader than upper, obliquely and excentrically mucronulate or rostellate, glabrous; gland basal, minute, obscure or absent. Inflorescences simple, 1 per node; peduncles usually 3–6 mm long, glabrous to sparsely puberulous, ebracteate at base; heads globular, (15–) 20–30-flowered, golden, slightly resinous. Flowers 5‑merous; sepals c. 1/2–2/3-united. Pods linear, to 6.5 cm long, 3–4 mm wide (4.5 mm in N.S.W.), firmly chartaceous, brown, glabrous, slightly resinous. Seeds longitudinal, oblong, 3.5–4 mm long; aril oblique.


Grows in sand in open woodland, sometimes forming almost pure stands.


Qld: Burncluith–Stockyard road, Barakula Forest, V.Hando 4 (PERTH); ‘Rockwood’ c. 32 km SW of Chinchilla, L.Pedley 3013 (BRI, NSW). N.S.W.: Carpet Snake Ck, c. 18 km NW of Torrington, J.B.Williams (BRI, NE, NSW, PERTH).


A specimen from near Rolleston (R.Story & G.Yapp 299, BRI) is atypical in having peduncles c. 13 mm; its very narrow phyllodes have a widened lower margin which is typical of the species. This specimen was referred to A. johnsonii by L.Pedley, Austrobaileya 1: 245 (1980).

Closely allied to A. johnsonii and A. barakulensis; also close to A. pilligaensis and A. islana. Resembling A. gittinsii and narrow phyllode forms of A. wilhelmiana.
