Hi Jenny, I've suggested longifolia but to be honest, I'm not entirely sure, is the plant still at this location?? If so would you be able to get more detailed photos of the flowers, as A.melanoxylon is also a possibility but it doesn't seem to quite match either....... :)
Hi Tapirlord, We'll have to wait until its flowering again to check if its still there. As you are aware we have removed lots of weed species so I'm not sure if this is still there.
Most Likely Longifolia but i'm not 100% convinced from the photos, and the wattle doesn't appear to still be at this site. So i'll just confirm Acacia Sp, :)
