Hm, hard.
There are a number of non-local Acacia invading the northwest slope of Mt Majura from the Federal highway plantings.
I first thought A boormanii (phyllode with a short oblique point, inconspicuous mid vein) but phyllodes are longer (30-80mm) than description also inflorescence seem to not fit...
Not a local Acacia i think.

The suggested species Acacia kettlewelliae is shown here on CNM as a local species, however, the species is not listed in the ACT Census of Vascular Plant Species (August 2019 version). I haven't come across it on Mts Majura / Ainslie - at least not consciously.
Best perhaps to collect a sample?

Yes good Idea to collect a sample and drop off to Dave Albrecht at the CSIRO herbarium it is only my best guess - I think Acacia Kettlewelliae grows along the Murrumbidgee In teh ACT and this specimen was probably planted.

I wonder why the species is not included in the Census although it is known to occur (naturally?) along the Murrumbidgee in the ACT; I'll make an effort to collect a sample today from the majura specimen.

if this is Acacia kettlewelliae, then its not a new record for the ACT: there are two herbarium specimens, one from Pierces Creek area and one from Naas River valley.

I went to the location and could only find 3 small Acacia boormanii about 1m+ tall; see Acacia boormanii (Snowy River Wattle)

I think it is A boormanii. There are several records of Snowy River Wattle SRW nearby. I removed (cut&spray) some SRW recorded by Jane in that area but must have overlooked this specimen. Because SRW has been planted along the Fed H'w there will be a continuous incursion of this non-local wattle. I predicted years ago that SRW will become the"new Cootamundra Wattle" CW since it is being used for residential gardens and public landscape work to replace the invasive CW.

Agree A. boormanii. Tho it may be invasive, I have it in my garden, flowers August.

M
all my next door neighbours planted it.
And I convinced them years ago to get rid of the Cootamundra wattles. I should have suggested replacements other than environmental weeds...
