If you SERIOUSLY want to identify plants you must take note off flowers, time of year it does what, height, local environment and just about everything you can think of. Its hard and as someone else said missidentification can have DIRE results, HOWEVER if you seriously want some accacia why don't you get some seeds??? They grow quick and if any people a really considering themselves "SPIRITUAL" or "ENLIGHTENED" i'd think they myte stop ripping off nature and screwing with the ecosystem to get their entheogenics(NOT suggesting you are Dude)I'm hoping we may all start to influence each other and spread the word to treat the woods a little better, these power plants have become WAY popular in the last decade and we have far too many "Happy Campers" tramping through without hearing nature and sadly a LOT of these sacraments are on the endangered list now(DEMON EST DEUS INVERSUS!!)Pity, i have seeds of an accacia so strong it needs no extraction but am too scared to reveal what it is as its dying out,(no-one seems to know it so im growing JUST to help save it)-i may suggest if one NEEDS to extract such either go for cane toads(YEUCH!) or at least grow your own and aim at those that contain alkaloids in the leafs
