The legume, Hoffmanseggia glauca was studied anatomically to clarify interpretations of its structures. Experiments were also conducted with the underground structures as a source of aqueous extracts used in determination of allelopathic effects on selected dicots. Comparisons were made experimentally in an effort to explain inhibition of cotton growth as observed in the field. The data collected during the course of this study provided a basis for those comparisons. Difficulties in obtaining viable H. glauca propagules complicated work in the study. This project was undertaken to increase information leading to potential uses of these native plants as sources of chemically active substances for use in biocontrol of other plants
