Acacia deltoidea subsp. ampla R.S.Cowan & Maslin
Fabaceae
Known from two localities in the Admiralty Gulf area, W.A.
Phyllodes inequilaterally elliptic to elliptic-ovate or triangular, broadest at or below middle, 10–20 mm long, 5–7 mm wide, acute, mucronate, scarcely pungent, thinly coriaceous. Peduncles 18–25 mm long, glandular-puberulous, normally with narrowly lanceolate bract above middle; bracteoles not exserted in buds.
Grows in woodland on sandstone.
W.A.: base of Bougainville Peninsula on E shore of Admiralty Gulf, P.A.Fryxell et al. 4782 (BRI, CANB, PERTH).
The differences separating subsp. ampla from the typical subspecies are mostly quantitative but they combine to produce a quite different-appearing plant.
