Nope thats a Eucalypt not an Acacia...
good luck finding a good Acacian candidate though!... whats your area? if you dont mind me asking. or just pm me
look up photos of these trees: Acacia Obtusifolia, Acacia Acuminata, Acacia Floribunda, Acacia Bakerii (marblewood), Acacia longifolia, acacia maidenii and Acacia Mucronata...theres many more that contain DMT though. I would go on Nen's improving Acacia information thread its in the open discussion section. its the goldmine for acacia spice related info on the web
if your in NSW, vic, or QLD then obtusifolia is probably your best bet if you can find it, or the floribunda seems to be getting successful reports and is endemic to many areas in vic and NSW.. they are planted in lots of urban areas and should contain around 0.4% DMT if any at all. I have had no success with floribunda
If your over in WA then Acacia Acuminata, Acacia Acuminata subs. Burkitti and Acacia Neurophylla are your best bet. WA is lucky in that these are easy enough to find
