The interest in the existence of various strains of rhizobia led the auther to a systematic study in that the classifying of rhizobia into species or subtypes on the basis of characters in artifical media is followed by the reexamimation on their behavior to legumes - the cross-inoculation, strain variation, and host specificity. In this part the results concerning the morphology of one hundred and three rhizobial strains isolated from various soils and legumes (twenty-nine genera) are described. Bacterial strains of lupine-group, Indigofera, Styphnolobium, and some of soybean and cowpea-group, show characteristic elongated forms on the yeast-water mannitol agar (five day's incubation at 28℃), whereas all others are observed as usual or small rod forms. Flagellation can hardly be used as a basis for classification, because any of the strains used is not found to be distinctly monotrichous.
