Synonymy: Racosperma dictyophlebum (F. Muell.) Pedley, Austrobaileya 2:347 (1987).

Common name: None

Description:
Erect, compact, spreading, glabrous, resinous shrubs 1-4 m high, sometimes rather open and straggly with a short trunk and long arching branches, foliage appearing whitish to pale green; branchlets resinous, slightly pustulate, slightly angular or ribbed; bark grey-brown, smooth on branches, rough at the base.

Phyllodes oblanceolate or more or less narrow-elliptic, 2-7 cm long, 5-15 mm broad, straight or slightly curved, coriaceous, viscid, glabrous, sometimes scurfy or pruinose, 2 (rarely 3) prominent longitudinal veins, lateral veins numerous, conspicuous, raised and anastomosing; apex obtuse but minutely mucronate; glands basal.

Inflorescences simple and axillary, solitary or twin; flower-heads globular c. peduncles 15-20 mm long viscid, glabrous; flowers 5-merous.

Legumes oblong, 5-9 cm long, 12-15 mm broad, flattish but raised over seeds; thin, light brown often with a shining varnished appearance, margins vein-like straight. Seeds transverse in legume; funicle short, folded, aril oblique, small.

Distribution:  Scattered in the northern part of the State from the far North-Western region, eastward to the Lake Eyre region in the Simpson Desert area. In open woodland or hummock grassland, associated with Triodia basedowii. Soils; mainly in red siliceous sands. Rainfall 125-200 mm. Also W.Aust., N.T. and Qld. S.Aust.: LE. Flowering time: April — September.

Related taxa: Acacia montana (sp. 65) is similar in phyllode characters having 2 prominent veins with fine reticulate lateral veins, but the phyllodes are usually much shorter; and the legumes are densely covered with white-woolly hairs.

Taxonomic notes: Acacia melleodora Pedley (1978) agrees in many respects with plants from the North-Western region identified as A. dictyophleba. Further investigation is needed to clarify the position of A. melleodora for South Australia.

Cultivation: The large, deep yellow, globular flowers make this shrub an attractive ornamental species. Suitable for dry inland areas in open well drained position or sandy soils.
