This thesis consists of six chapters: I. A review of nodulation in the family Leguminosae. This updates the classic work of Allen & Allen (1981) and includes new nodulation records (296 species). The doubtful nodulation status of some species is discussed, and the taxonomic implications are considered. The distribution of nodulation within the Leguminosas was found to be consistent in some tribes, groups and genera: this together with nodule morphology and structure are of considerabletaxonomic value. II. A study of nodule structure, from woody legumes, with special emphasis on caesalpinioid species. This revealed many symbiotic features different from those assumed to be general in legumes,although very similar to those reported in Parasponia, (the only genusof non-legume known to fix nitrogen in symbiosis with rhizobia). In all caesalpinioid, some papillionioid, but no mimosoid species, the bacteria are kept inside infection threads during the whole nitrogen fixing period. III. Root infection and nodule development in a species which does not consistently produce root hairs, Mimosa scabrella. A broad survey of root hair production and location in legumes roots was conducted as a basic study, choosing Mimosa scabrella for this study. Bacterial penetration into roots was found to occur via intercellular movement, prior to the intracellular infection; bacteria inside the cells were enclosed by structure which resemble infection threads; nodule initiation and development apparently does not differ greatly from that..
