amino acids is a Vell known phenomenon in animals and has been interpreted as the detoxication of otherwise poisonous substances. The formation of indoleacetylaspartic acid is the first instance of a similar reaction in plants which has come to the attention of the authors. The significance of the reaction in the physiology of the pea is not yet understood. However, the marked difference between plant species with respect to the biosynthesis and utilization of indoleacetylaspartic acid suggests an approach to the problem of selective herbicidal action which may prove useful. The authors wish to acknowledge the technical assistance of A. W. H. Van Ysselstein. LITERATURE CITED 1. ANDREAE, W. A. Communicated at the Congr. Intern. Bot., 8th, Paris. Sect. 11/12: 151. 1954. 2.
