Acacia cuspidifolia Maslin, Nuytsia 4: 79; 80, fig. 4 & 100, fig. 10 (1982)
Wait-a-while , Bohemia
Bushy shrub or gnarled tree 3–7 m high. Branchlets glabrous or subglabrous. Stipules spinose, absent from some nodes, shallowly recurved, 2–4 mm long. Phyllodes mostly narrowly oblong-oblanceolate to linear, 3–6 cm long, 2–5 mm wide, narrowed at base, pungent, glabrous to subglabrous; midrib prominent; lateral nerves obscure; gland 0–5 mm above pulvinus, additional gland often at base of cusp. Inflorescences simple, (1) 2 per axil, initiated synchronously with phyllodes on new shoots; peduncles 15–20 mm long, glabrous or hirtellous; heads globular, 23–32-flowered, pale yellow. Flowers 5-merous; sepals free to 1/2 united. Pods narrowly oblong, to 9 cm long, 1–2 cm wide, chartaceous, finely transversely reticulate, glabrous. Seeds transverse to oblique, widely elliptic to widely ovate, 6–7.5 mm long, dull, brown, exarillate; funicle strap-like.
Extending from Minilya Stn E to near Mundiwindi and S to near Ballythanna Hill, W.A. Favours open floodplain areas in clay or loam.
Perhaps most closely allied to A. pickardii but distinguished from this species, and from other members of the ‘ A. victoriae group’, by its pungent, flat phyllodes.
