Acacia barringtonensis Tindale

Common Name

Barrington Wattle




Occurs in the Great Divide from Gibraltar Range Natl Park S to Barrington and Gloucester Tops, northern N.S.W.


Usually a shrub 1–3 m high. Branchlets angled at extremities, with indumentum of ±sparse minute (< 0.1 mm long) appressed straight hairs. Phyllodes narrowly elliptic to narrowly oblong-elliptic, usually 5–10 cm long, 5–15 (–20) mm wide, thin, with indumentum as on branchlets but denser on young tips, occasionally some glabrous, 1-nerved; lateral nerves obscure; gland not exserted, normally 5–23 mm above pulvinus, often connected to midrib by a fine oblique nerve, with margin normally slightly recessed at gland. Inflorescences racemose; raceme axes usually 1.5–3.5 cm long, with indumentum as on branchlets but often denser; peduncles 2–5 mm long, with indumentum as on raceme axes; heads globular,
8–16 (–20)-flowered, golden; bracteoles similar to A. caesiella. Flowers 5-merous; sepals c. 4/5‑united; ovary densely pubescent. Pods stipitate, to 8 cm long, (7–) 10–12 mm wide, firmly chartaceous, dark brown, glabrous or with sparse minute appressed hairs, often ±pruinose, dehiscing unilaterally. Seeds longitudinal, oblong-elliptic, 4–6 mm long, slightly shiny, black; aril clavate.


Grows in soil derived from granite or basalt, near creeks or on margins of swamps, in Eucalyptus forest or woodland, usually at altitudes above 1000 m.


N.S.W.: Gloucester Tops, R.Coveny (NSW95769), Mulligan’s Hut, Gibraltar Range Natl Park, R.Coveny 2229 (NSW); Barrington Tops, at top of Moonan Brook track, I.R.Telford 2583 (PERTH).


A specimen from the Upper Manning R., Barrington Tops, (D.F.Blaxell 26 & R.G.Coveny, NSW) is slightly unusual in being a tree to 5 m high and with phyllodes to 13 cm long and racemes to c. 6 cm long.

Acacia barringtonensis together with A. caesiella, A. clunies-rossiae and A. dorothea forms a group of related species which are discussed by M.D.Tindale, Telopea 1: 72–74 (1975). Related to A. covenyi, fide M.D.Tindale, Telopea 1: 435 (1980). Acacia polifolia from Qld is closely allied to these species.
