Description of Certain Bacteria Obtained from Modules 

 OF Various Leguminous Plants. 



By Severance Bukrage. 



(A preliminary study on the constancy of the distribution of bacterial species in definite 

 species of leguminous plants.) 



It has been quite thoroughly proven that several different species of 

 bacteria may be found in the nodules of various leguminous plants. The 

 following questions, however, have not, it seems to me, been definitely 

 settled with regard to them: 



Does the same species of bacteria always occur in the same species 

 of legume? 



Does the same species of bacteria always occur throughout all the 

 nodules on the same plant of any species of legume? 



Does the same species of bacteria always occur in the nodules of all 

 the plants in a field planted with one species of legume?
