life 'history of these Iwo groups of organisms would 

 make it. possible to s<)y definitely whether they are. 

 indeed, two di.stinct spe<'ies or merely different types 

 of growth of the same organism. 



(5) Bacillus radicicola is closely relat^ed to B. ra- 

 diobacier. The generic name Rhizohium is to be 

 rejected. The correct .systematic position of both 

 species is in t)he neighborhood of B. aerogenes and 

 B. coli. 



(6) Bacilbis radiobacter seems to be regularly pres- 

 ent in the root nodules of legiimiuous plants, .stimu- 

 lating development and activity of the nodule bacteria. 

 On account of its similarity to B. radicicola. it has 

 been repeatedly mistaken for t|ie nodule-producing 

 organism in the cowpea-soybean group, whose bacteria 

 it outranks very^ considerably in the development on 

 the plates made from the nodules. By its brown 

 growth on potato, B. radiobacter can be ea.'^ily dif- 

 ferentiiated from B. radicicola.
