Pretty sure it is T.orientalis, it is quite common in this creek system.

Thank you!

That near blackish colour is closer to the introduced species, T. Latifolia than to T. Orientalist.
hope I am wrong !

Perhaps some closer focused images are in order?

Hope it's not T. Latifolia! I don't have any more photos, but can try to be there next time it is flowering.

changed to Typha latifolia, which has been recorded from southern NSW.
I have seen a lot of T. orientalis and none were 'black' like this, which is signature colour for T. latifolia.

Did you mean to reconfirm the ID Jane? I'm happy to go with your expertise, though I'm a bit hesitant given the location. More images would be fantastic.

Yes, I did mean to re-confirm: thanks for picking that up.

I am a bit concerned calling this orientalis, given that the colour of the spike (black-brown) is distinctive for latifolia: and is actually one of the characteristics used in FloraVic to separate latifolia from the two native species.
More photos won't change the colour: closer inspection needed.
Can you explain why the location is a concern for you, Ciaran?

I had thought this species was more or less a weed of the urban enviroment, and this site up in the alps would be quite a ways from other records. However there are a couple of other DPS records from neighbouring valleys so perhaps it is already here. It is a shame as the habitat up here is of high quality.

if in the area, the best thing to do is to chop off the flowering spikes before seed is distributed: propagule pressure is a major reason for successful invasion, and these flowering spikes carry loads of seeds in the hundreds of thousands.

Thanks for alerting us. Sounds like it needs removing!
Last summer was the first time we'd seen it.
It was very limited in distribution - only in the cluster photographed.
We'll see if we can find it before it flowers again.
