Family

Fabaceae

Distribution

Known only from Bacon Ra. and Beddome Ra., southern N.T. and S.A. near the N.T. border.

Description

Shrub or tree 3–7 m high. Branchlets ±glabrous to appressed-puberulous. Phyllodes narrowly linear to linear-oblanceolate, mostly very shallowly incurved, 5–10 cm long, 2–4 mm wide, with an acute to short-acuminate and straight to uncinate apex, coriaceous, khaki green to greyish green, glabrous to sparsely appressed-puberulous, with numerous closely parallel obscure nerves. Inflorescences 2–5-headed racemes; raceme axes 1.5–5 mm long, appressed-puberulous; peduncles 5–9 mm long, puberulous; heads globular, 4 mm diam., 13–18-flowered, resinous. Flowers 5-merous; sepals free. Pods linear, flat except slightly raised over and constricted between seeds, to 15 cm long, 5–6 mm wide, coriaceous, distinctly reticulate, glabrous. Seeds longitudinal, oblong, 5.5 mm long, dull, brown-black; funicle gradually enlarged towards minute, apical aril.

Habitat

Grows in skeletal alkaline soil in gullies and rocky slopes on low hills; locally dominant in tall open shrubland or with members of the ‘Acacia aneura group’.

Specimens

N.T.: Beddome Ra., P.K.Latz 5238 (BRI, CANB, PERTH); 4 km E of Dead Bullock Dam, Henbury Stn, P.K.Latz 9402 (NSW, PERTH). S.A. 10 km ENE of Mt Mead, Tieyon Stn, 17 Aug. 1992, P.K.Latz 12465 (DNA).

Notes

Seems allied to A. calcicola which is most readily distinguished by its flower-heads with more flowers and by ±woody and moniliform pods.
