Nealie , Nelia , Broken Hill Gidgee , Myall
Shrub or tree 3–7 m high with habit similar to that of A. papyrocarpa . Branchlets sometimes pendulous, appressed-puberulous, glabrescent. Phyllodes linear, subterete to flat, 5–11 cm long, 1–2 mm wide, acuminate with a fine, delicately curved, innocuous point, appressed-puberulous, with numerous closely parallel, indistinct nerves. Inflorescences 2–6-headed racemes or simple in axillary clusters; raceme axes minute; peduncles 4–7 mm long, appressed-puberulous, sometimes with reddish resin-hairs intermixed; heads globular, 4–5 mm diam., c. 25-flowered, golden; bracteoles spathulate, not ciliate. Flowers 5-merous; sepals free; petals glabrous. Pods submoniliform, to 10 cm long, 3–5 mm wide, chartaceous, smooth, finely appressed-puberulous to glabrous. Seeds longitudinal, elliptic, 4.5 mm long, glossy, brown-black; aril small.
Occurs in western N.S.W. W of Hillston and N of White Cliffs, extending into S.A. to Oakbank Stn and Netley Gap; also in north-western Vic. near Merbein and Nathalia. Grows in solonized brown and red soils, in low woodland and tall shrubland, sometimes associated with chenopods, Casuarina cristata or Acacia aneura .
A.B.Court, in J.H.Willis, Handb. Pl. Victoria 2: 237 (1973), refers to ‘A. sp. affin. A. sowdenii’ from north-west Victoria; further work is needed to confirm the status of these populations. Current indications are that most seem referable to A. loderi, however, hybridity with A. melvillei (which was referred to by A.B.Court, op. cit. 238, as A. affin. pendula ) should not be discounted for at least some plants from this area.
Closely related to A. papyrocarpa which, as presently interpreted, does not extend farther E than the South Flinders Ra. in S.A.
