Fig. 28. a. Azotomonas insolita, NCIB 8627. 

 Peritrichous flagella of rather short wavelength. Many 

 individuals on the shde showed single flagella often 

 at the pole, as well as several flagella at the pole. 

 However, the peritrichous nature of the flagellation 

 seems unquestionable. The flagellation is very simi- 

 lar to some species of Rhizobium.
