Dave Albrecht from the CSIRO herbarium provided the following comment after Silke dropped off a specimen
I believe your specimens are Acacia paradoxa rather than A. howittii, as the stipules are spinose and the number of individual flowers within each head falls within the range of A. paradoxa (30 in your specimen, cf. 12-20 for A.howittii). The stipule length is at the bottom end of the range for A. paradoxa, however they are still considerably longer and spinose in comparison to A.howittii.
It is conceivable that Acacia paradoxa and A. howittii could hybridise, though this is most likely where both species are growing in close proximity.

Hi Michael, I'm not sure if this Acacia is also a paradoxa. The specimen I took to the ANBG were all from trees in the area behind Cobby St in Campbell and behind the War Memorial, not of this one. The ones I took to the gardens were are all IDed on CNM as A. paradoxa at the time, even though they very much look like hybrids. I think this one here looks more like a pure A. howittii.
