A new one for me. I was actually looking for Bidens pilosa (which I knew to be along Long Gully Road). I have now removed 98 plants of B. subalternans and 5 B.pilosa.

Thanks Mike I think I have been removing it thinking that it was the other Bidens. I think the only other ACT record is a 2014 record near the junction of the Molonglo and Murrumbidgee.

The leaves are quite different when you compare the two - see https://canberra.naturemapr.org/Community/Sightings/Details/4188265. I found the plants a few weeks ago but waited for flowers so they could be identified. They are included in the ACT weeds list on Collector so might be more common than you think.
