• Notes:
  • ⏲ According to Mergärt et al. (2002), this species is a later heterotypic synonym of Phyllobacterium myrsinacearum (ex Knösel 1962) Knösel 1984. Publication: Mergaert J, Cnockaert MC, Swings J. Phyllobacterium myrsinacearum (subjective synonym Phyllobacterium rubiacearum) emend. Int J Syst Evol Microbiol 2002; 52:1821-1823. 🇧🇪
  • ❗ Phyllobacterium rubiacearum is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Phyllobacterium.
