How are A. longifolia and A. floribunda distinguished? This has broader phyllodes than 4391762, and flowers are maybe fractionally yellower. Mt Painter Reserve slope between tanks and Cook memorial.
Yeah - I haven't nailed it yet but there is the lighter colour of the floribunda flowers and that they are spaces between the flowers on teh main flower stem, where as in longifolia it is a yellow and they are clustered together so that you can't see space between the flowers. That said I am still uncertain about this one
