L Costermans (1994) Native Trees and Shrubs of South-Eastern Australia: sparsely hairy to glabrous phyllode. Otherwise features such as phyllode with one central vein to point and peduncles solitary or several on very short common stalks seem to confirm the id. Distribution according to Costermans South Australia; not Southern Tableland / ACT ie not a local. It is not listed on the ACT Census of Vascular Plants, and a new description for Mt Majura. I propose to collect a sample to confirm the id by a botanist and for the herbarium.
Thanks Barb, that escaped me. I didn't follow through with the identification because I was very sick around that time I noted Greg Baine's record from Federal Highway from the 18 October 2022. I think this Acacia species was part of the Fed highway plantings and is possibly not a local species. Need to discuss this with Greg and other botanists. w
