  • 🙅 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of the name to be applied to this species. The name is on LoRN because of the recorded risk group of the genus.
  • 🧍 Plant pathogenic according to Bull et al. (2007). Publication: Bull CT, De Boer SH, Denny TP, Firrao G, Fischer Le Saux M, Saddler GS, Scortichini M, Stead DE, Takikawa Y. Comprehensive list of names of plant pathogenic bacteria, 1980-2007. Journal of Plant Pathology 2010; 92:551-592. 🇺🇸
  • 🧍 Rejected name (Opinion 14); later homonym of a protozoan genus Rhizomonas. Publication: Judicial Commission. Judicial Opinion No. 14. Int J Syst Bacteriol 1954; 4:156-158.
  • 🧍 The name Rhizomonas suberifaciens van Bruggen et al. 1990 is illegitimate because it is placed in an illegitimate genus (see: Rhizomonas). However, according to Rule 32b, the specific epithet (suberifaciens) is not rendered illegitimate. So, the combination Sphingomonas suberifaciens is a correct name and must be used because it is the single legitimate, validly published name.
