A report that sheep fed on a perennial grass, Phalaris tuberosa L., developed a condition known as staggers led to the investigation of a related species, P. arundinacea L., and the subsequent isolation from it of 5-methoxy-A-methyltryptamine (XVIII R = H) (116). 5-Methoxy-iV.A-dimethyltryptamine (XVIII R = Me) also occurs naturally, and has been isolated from Dictyoloma incane-scens DC. (40). Both bases have recently been shown to be present in the bark of Piptadenia peregrina Benth. (73a).
