Acacia praetermissa Tindale, Telopea 2: 113; 114, fig. 1 (1980)
Suberect shrub to 1.8 m high. Bark smooth, bluish grey, blotched. Branchlets terete, purplish brown, slightly pruinose; lenticels visible. Phyllodes spreading, very narrowly oblanceolate-elliptic, falcate, 7.5–17 cm long, 3–16 mm wide, with prominent midnerve and 2–4 subprominent, parallel nerves, the minor nerves 1 or 2 per mm, loosely anastomosing; gland 1, basal, adjacent to pulvinus. Spikes 1–2.7 cm long, golden. Flowers loosely arranged, 5-merous. Calyx 0.5–1 mm long, dissected to 1/4–1/2, sparsely fimbriate towards apex; corolla 1.3–1.8 mm long, dissected to 1/3–1/2, glabrous; ovary sparsely pilose. Pods narrowly oblanceolate to linear, straight-sided or slightly constricted between seeds, flat, 4.5–10.5 cm long, woody, obliquely to longitudinally and reticulately nerved, opening elastically from apex; margins thickened. Seeds slightly oblique, elliptic-oblong or elliptic to orbicular, 5.5–7 mm long, brown; areole open; funicle-aril conical.
Restricted to the Noonamah (Darwin) district and Pine Creek–Emerald Springs region of the N.T., although poorly collected. Usually on hillsides in lateritic soil or sandy silt in eucalypt woodland. Flowers Feb.–Aug.
Acacia praetermissa can be distinguished from members of the ‘ A. stigmatophylla group’ by the very loosely anastomosing minor nerves between the 3–5 parallel main nerves, the ridges of the branchlets which are not minutely crenulated, and the compressed-orbicular seeds.
