P. arundinacea now has world-wide distribution. It is regarded as native to both North America and Eurasia, but this is debated and it appears that the populations in North America are made up of a mixture of cultivars of both those that were introduced from Europe and indigenous varieties. Chemical properties Specimens contain varying levels of hordenine and gramine. Leaves of P. arundinacea contain DMT, 5-MeO-DMT and related compounds. Levels of beta-carbolines and hordenine have also been reported.
