My first thumbnail picture :-)
17 mm to give scale.

Assuming it was from NSW, ACT, or Vic, I got down to about 20 species in the program Wattle2 that were possible. Acacia boormanii seemed the most likely.

It didn't look like any Acacia boormanii in the area but it could come from a different locality. I will have to go and do some measurements.

I will try again. Did you notice if the flower stalks on individual flowers were hairy, and if so, what sort of hairs? That will cut down the possibilities.

I have enlarged a section of the photo. I will try to get more suitable pictures.

Hi Mike. I have just worked on this for about half an hour and cannot get any sensible ID. I used the varsion of Wattle2 that does not require Java.

If you really want to know what it is, take it into the herbarium, in flower and in pod. Your photos of flower buds will help them to count the flowers.

Hi Betty, thanks for your patience on this. I have done some measurements: phyllode length 30-45mm, width 3-4mm; gland 6mm; 10-12 flowers per head; 7-17 (avg 10) heads per stem. I am thinking Acacia fimbriata seeing most of the nearby wattles are also non-local.

Hi Mike I will have another go now I have exact measurements to work on. I have already considered Acacia fimbriata. The diagnostic for it is the fringe of hairs round the margin of the leaves, which is what its specific name refers to. I saw no evidence of that even when I enlarged the photos.

With a hand lens I can see hairs on the margins particularly near the stem but I don't know if this counts as 'fimbriate' I have added some macro shots.

I had been looking at keys and Workd Wide Wattle diagrams of diagnostics. When I looked at the description of Acacia fimbriata in Plantnet just now, it stated that the phyllodes are occasionally hairless! Hairy edges is a key characteristic.
