really need clearer shots still mate... a shot of the whole tree would be really helpful. its still really hard to make out much to be honest.. every phyllode in that pic is blurry.. the only moderately clear part of the image to go by is the flowers so its really hard to i.d going by them alone
there are many of acacia's that share very similar attributes and can easily be mistaken for one another.. as i can definitely attest to from recent experiences... need to see the finer details. my guess as i said would be acacia iteaphylla, although the phyllodes in your pic are a little greener.. usually iteaphylla has a greyish bluey green colour to the phyllodes.. but that may well be to do with the lighting in your picture... it really does look pretty much identical other than that going by what you've posted so far.. the flowers look promising
how long and how wide are the phyllodes? what colour are the stems? iteaphylla has green stems often with reddish colouring on the side facing up.. i guess this could be to do with the sun? the phyllodes are quite spaced from each other too. anyways.. there's no record of DMT content in iteaphylla anyway as no chemical analysis has been published, but I will be able to let you know by tomorrow night if my specimen is carrying alkaloids as I'm currently doing an extract.. but even then.. thats only one specimen... maybe give it a go and see if anything comes
if your in south australia though your best bet would be Acacia Burkitti.. a subspecies of Acacia Acuminata... this species is known to contain DMT in similar amounts to Acacia Acuminata and is widespread throughout S.A. I would be pursuing that species if I were you.. use phyllodes, or prune a few branches.. don't use the trunk bark unless you can find a dead or obviously dying tree
Here's a pic of Acacia Burkitti .. and below that flinders wattle
hopefully these can be of help. that's all i can really tell ya in terms of S.A tryptamine containers.. Nen888 is very knowledgeable on Acacia's I would highly recommend reading through his thread "Trying to improve Acacia information" up the top i the sticky section..it has pretty much everything you need to know for your area, and he's always very helpful in answering queries!
