One hundred and seventy‐nine yellow pigmented Gram negative rods, including 170 new isolates obtained from a variety of habitats, were investigated and the results analysed by computer. Nine phena, embracing 146 strains, were distinguished. Five of these comprised 88 of the 109 non‐motile, aflagellate strains (i.e. ‘atypical cytophagas’) and they should be assigned to a re‐defined genus Flavobacterium . A separate phenon containing 41 of the gliding isolates was delineated which should be ascribed provisionally to the genus Flexibacter . Only low G + C contents have been recorded for representative strains from these six phena but one strain (which would have been ascribed to Flavobacterium ) had a high G + C content; such organisms (both peritrichous and non‐motile) should comprise a separate genus Empedobacter (Brisou). The remaining three phena respectively comprised strains of Erwinia herbicola , pseudomonads and unclassified aflagellate isolates; their taxonomic position is discussed.
