Hi Betty I'm a bit confused. If the other Acacia a few days ago was A. boormanii, then this one definitely isn't the same species. This one has much wider and longer phyllodes. They are also angled forwards whereas the other plant has backwards angled ones. This tree is much larger -approx 5-7m high and the flowers are not as densely spaced. The other plant is one big cotton ball of flowers with the leaves just managing to poke through, not so on this one. Are there any other possibilities?
I could take some specimens to the Bot Gardens, I was planning to go there anyway with the other acacia. See what they think.
Do so. I could not see the angled branchlets in the other photos, so it could be they that are wrong. The books say that Acacia boormanii is a shrub or tree to 4.5 m, 'leaves' 1.5-9cm long, 1-3mm wide. Trying to measure leaves off a photo with not much idea of scale is a nightmare. How dense the flowers are is not used in identification.
