An observation on the culm (stem) is useful, whether round or triangular-ish. If round, then its Carex tereticaulis; if triangular, then Carex appressa.

Not that C.tereticaulis occurs around the city

Recorded on Ainslie-Majura, at least

And I suspect is under recognised and under reported.

Oh interesting, I wasn’t aware of that. I do agree that it’s under reported though, I find it pretty frequently along creek margins in Namadgi. Still I’d be surprised to see it around Aranda, there’s not really enough water

I found it in a marshy area in the southeast corner - quite a bit of water around.

Permanent? or just a product of the last few wet years? For C.tereticaulis you need the former.

Good point. It does dry out but doesn’t take much to get mushy. I guess the question if it can sustain marshy plants. That’s a definite near our large dams but perhaps not in the area fully covered in prickly tea tree. Actually it is a bit hard to know because the tea tree is so dense in many areas that it’s only possible to skirt around the edge.

My experience of Carex tereticaulis is that, once established, it is quite tough and can survive long periods ( even years) without being flooded or on marshy ground: like dam walls during drought. But getting established may be different.

Ahh dear, giving me a run for my money here Jane! I still stand by what I’ve said though, C.tereticaulis will only establish in permanent (arguably semi-permanent) water sources: Dams, creek margins, swamps etc. This is different to C.appressa which will occur in all those above and also in seasonally wet drainage channels and soaks which is what we have here.
