Another sleeper weed?

Following discussion of Koelreuteria vs Koelreuteria elegans I have taken additional photos. The fruit is elongated rather than ellipsoid and the leaves are esssentially pinnate though some of the larger leaflets are pinnate (mentioned in Wikipedia). A good description of K. elegans is given in https://weeds.brisbane.qld.gov.au/weeds/golden-rain-tree and this is not it. Other sources say K. paniciulata can be bipinnately compound, and to confuse the issue there is K. bipinnata sometimes recognised as K. paniculata. https://www.botanybrisbane.com/plants/sapindaceae/koelreuteria/koelreuteria-elegans-subsp-formosana has pages of photos showing leaves and fruit, saying related species "K. paniculata has mostly pinnate leaves but also some bipinnate.". @abread111 mentions plantings of K. elegans subsp. formosana on Phillip Ave but I wonder if they are in fact K. paniculata as listed in https://www.cityservices.act.gov.au/__data/assets/pdf_file/0004/1378543/Municipal-Infrastructure-Standards-25-Plant-Species-for-Urban-Landscape-Projects.pdf.
I am not a botanist so go by the descriptions I find rather than keys. The genus is not in NSW Flora Online although K. elegans subsp. formosana is an environmental weed in northern NSW spreading from Queensland.

Perhaps a field trip to Forest 104 - Goldenrain Tree at the National Arboretum would be useful.

Thanks for your documentation Mike, I'm pretty satisfied with this effort of research, seems like a good conclusion.
