Interesting post thanks plantatron..

regarding floribunda.. its a tricky one and I think may depend on area/strain. Trees from certain areas are consistent in yielding dmt.. other areas the trees seem to be devoid of it. I've done a lot of tests on it and found it to be highly variable.. sometimes it yields extracts that are probably almost entirely tryptamine, nmt or betacarbolines (as was the case with a recent test)

the other thing to take into consideration is that young plants may not have dmt.. in the "trying to improve acacia information" thread (a link in my signature) I remember nen mentioning a test on a young a.phlebophylla that was void of dmt and just contained simple tryptamine so that may apply to other acacias.
