Acacia Confusa: Bad info

So I was doing some research in a handy dandy book I have " The Encyclopedia of Psychoactive Plants and found another plant with a higher concentration of DMT. Though Acacia confusa does rate a high percentage of DMT, Diplopterys cabrerana contains 1.75% DMT in its fresh dried leaves. I dont know where that article received is information but clearly it is not the highest contain source known to mankind. It is though true that Acacia confusa recently was studied to find out what kind of active compounds were located in the plant, and DMT was one of those.
