Acacia cuspidifolia Maslin
Acacia cuspidifolia Maslin
Wait-a-while, Bohemia
Fabaceae
Extending from Minilya Stn E to near Mundiwindi and S to near Ballythanna Hill and near Meekatharra, W.A.
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, (2–) 3–6 (–7.5) cm long, 2–5 mm wide, narrowed at base, pungent, glabrous to subglabrous; midrib prominent; lateral nerves obscure; gland 0–5 mm above pulvinus, with an 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.
Flowers mainly Oct.–Dec. but sometimes in other months.
Favours open floodplain areas in clay or loam.
W.A.: c. 5 km S of Yaringa on North West Coastal Hwy, A.M.Ashby 4491 (CANB, K, MEL, PERTH); 33 km along road from Mundiwindi to Mount Newman, H.Demarz 611 (PERTH); Byro Stn, 10 km W of Ballythanna Hill on the track to North West Coastal Hwy, B.R.Maslin 5167 (PERTH).
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.
