Acacia loderi Maiden
WATTLE
Acacias of Australia
Common Name
Nealie, Nelia, Broken Hill Gidgee, Myall
Family
Fabaceae
Distribution
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.
Description
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, 0.9–2 (–3) 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, 0.1–2 mm long; peduncles 4–7 mm long, appressed-puberulous, sometimes with reddish resin-hairs intermixed; heads globular, 4–5 mm diam., 25–36-flowered, golden; bracteoles spathulate, not ciliate. Flowers 5-merous; sepals free; petals glabrous. Pods submoniliform, to 10 cm long, (2–) 3–5 mm wide, chartaceous, smooth, finely appressed-puberulous to ±glabrous. Seeds longitudinal, elliptic, ±4.5 mm long, glossy, brown-black; aril small.
Habitat
Grows in solonised brown and red soils, in low woodland and tall shrubland, sometimes associated with chenopods, Casuarina cristata or members of the ‘Acacia aneura group’.
Specimens
S.A.: Danngali Conservation Park, Postmark, 2.5 km E of Outstation, 18 Sept. 1984, S.Barker s.n. (AD). N.S.W.: Fowlers Gap, N of Broken Hill, S.Jacobs 2305 (NSW, PERTH). Vic.: Cowra Stn, W of Merbein, N.A.F.Gibb 0820 (PERTH).
Notes
Closely related to A. papyrocarpa which, as presently interpreted, does not extend further E than the South Flinders Ra. in S.A.
A.B.Court, in J.H.Willis, Handb. Pl. Victoria 2: 237 (1973), refers to ‘A. sp. aff. A. sowdenii’ from north-western Vict.; further work is needed to confirm the status of these populations. Current indications are that most seem referable to A. loderi, but hybridity with A. melvillei (which was referred to by A.B.Court, in J.H.Willis, Handb. Pl. Victoria 2: 238 (1973), as A. aff. pendula) should not be discounted for at least some plants from this area.
