Looks a bit like Walwhalleya subxerophila. Did you collect a sample? Would be a good one for the herbarium to confirm.

Yes, I did. Where does it occur naturally pls? (Must be native?) I hope I didn't pull them all out....

I cannot drop it off for a few days unfortunately, but the doesn't make any difference? WS has red nodes, and the height looks right, as does the appearance of the panicle. So...... where the hell has it come from???

That is a good question. Given it is a species from west of the divide, I would assume seed has been brought in with soil eg. gravel for tracks or mud in vehicle wheel wells. Tragus australianus, also a western grass. Is present along much of the length of Parkes Way through to the airport, likely a part of the red gravels imported to fill the median strip. It's possible your plants are associated with the construction of the light rail.

I should add that the purpose for dropping it off at the herbarium is to get a verified ID (my ID could be wrong) and to formalise the record, especially important as this appears to be the first record of the species for the ACT.

I dropped the specimen off around ten days ago at the ANBG VIC. No word yet.

The wait time is highly variable. I am still waiting for IDs from several months ago.
