New location and rare location of high risk weed - great to deal with it now before it comes widespread
User's notes
Growing at edge of flood zone Ginninderra Creek. Plant sprawling, with ribbed stems, quite branched, inflorescence spikes in upper leaf axils, fruit clusters have many pointed tips

Quite a bad one if I am right and only a couple of prior ACT records so would be great to eradicate

It's a pleasure doing this job @Mike. If you don't agree with any of my suggestions, please help me improve by confirming the correct species.

Thanks everyone, including CarbonAl.
It does look very Rumexy but I drew a blank when I used the Plantnet key for that genus. Leaf has petiole shorter than lamina, and fruit are sharp beaked, not rounded like the photos for R saggitatus in Plantnet. Leaves are probably more triangular than hastate, and habit is sprawling rather than climbing but that maybe from its open surroundings. I'll pop a sample to herbarium for ID.

I've seen turkey rubarb a few times down the coast and it has never had fruit like this. Based on the fruit I think it's likely to be in Chenopodiaceae and possibly Einadia trigonos.
Well worth taking it to the herbarium as I don't think there has been a formal collection of that species from the ACT.

Thanks Ciaran, I did wonder if the the fruit and shape of the leaves looked like Einadia, but leaf shape looks very large for that one to me. I don't know if Einadia trigonos is actually native to the ACT, or brought in from elsewhere? But seems like a good suggestions, thanks

Thanks John - can you please keep us informed of Herbarium ID. It is definitely not Turkey Rhubarb, but seed head doesn't look right for Einandia - I first thought Fallopia convolvulus and then Emex australis but the seed head is not right for either of those - so I am at a loss.

ID has come back from ANHerbarium botanist. Since it's exotic, I'll clear the 2 plants away.
