This appears to be very similar to your previous sighting,

probably the same species. It needs to go to the botanic gardens too.

The other sighting was via the app, which told me it 'stopped working'. I have specimens.

I found some photos of Euphorbia dentata that look the same, but it seems to be variable in leaf. ALA has it as Euphorbia davidii. Weed in west and north NSW.

Mike are you able to control these plants of Euphorbia davidii yourself or do you need help?

Probably manageable if I can get people interested. It is beside the road so it would be good to get City Services agreement and some safety signs/cones. It is supposed to be glyphosate tolerant so it means pulling the plants (or seed heads) by hand.
