Glaukus & Sally are gonna be the ones who will be able to help you out with this.
Glaukus made the call with longifolia in you first post. (which looks to me to be correct)
And Sally actually grows obtusifolia. (& could even edit a wikipedia post, and i quote. "The reinous margins aren't always apparent on obtusifolia, particularly in winter. They do appear resinous (mine do anyway) during periods of rapid growth")
Seems to me they have more knowledge on this than you can poke a stick at .
Your new pics of plants, you say vary from around .5 metres tall to at least 2 metres- some 3
Look to me to be the same species as the ones in your first post. (Acacia Longifolia)
Although your third pic (the one next to the seed pods) still has me guessing.
The leaves look much more narrow, and flowers much paler than the rest. - Anyone able to help out?
I went through this list from wikiepdiea https://en.wikipedia.org/wiki/List_of_Acacia_species
The closest thing i could find matching the pics of your illusive friend was.
But once again unfortunately I'm no expert, just what I'm getting of the net.
I can't say for sure what it is.
Anyone able to help me/us on this one?
