Should be O'Malley or Mugga Mugga Nature Reserve. Wrong side of the road for Garran.

This photo appears to be A. cultriformis. The reasons are:
the size of the phyllode in relation to the stem is large;
the phyllode is glaucous;
there appears to be only one main vein;
there is a small hooked mucro on the top of the phylode

I will try to get some better photos but I think it is A, pravissima. The mucro is common to both A. pravissima and A. cultiformis and the second vein is not always obvious on A. pravissima. I aso look at the angle between the phyllode and the stem. Do these species hybridise? I know A. cultriformis is somewhat variable in phyllode shape.

Mike, they do hybridise but not commonly. I have only seen 2 plants where I suspected hybridisation. Did you use flash when taking the photo, as this sometimes affects the colouration of the phyllodes. I want to sort this out as pravissima, cultriformis and vestita appear to cause some confusion in photographs. i will call in and see the tree in the near future.

Another feature to look at is the location of the gland. This is clear in the second photo.

Photo added to show the two veins. Now I remember why I photographed this plant - there is an A. cultriformis about 5 metres away ( see Nearby sightings). They are quite different when you see them together.
