Notes:
- ⏲ According to Volpiano et al. (2021), this species is a later heterotypic synonym of Rhizobium pisi Ramírez-Bahena et al. 2008. Publication: Volpiano CG, Sant'Anna FH, Ambrosini A, de Sao Jose JFB, Beneduzi A, Whitman WB, de Souza EM, Lisboa BB, Vargas LK, Passaglia LMP.

- 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Garrity GM. List of changes in taxonomic opinion no. 35. Notification of changes in taxonomic opinion previously published outside the IJSEM. Int J Syst Evol Microbiol 2022; 72:5164.
- 📧 The e-mail address of the corresponding author given in the effective publication is not functional any more.
- ❗ Rhizobium fabae 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 Rhizobium.
- 🧬 The phylogenomic assignment score of this taxon is 0.15646 (N = 9).
- 😷 The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1. — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
- 🎓 Name mentioned 6 times in PubMed until 2025-06-04.
- 🙅 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 pathogenicity of other species in the genus.
- 🧍 See also: Publication: . Erratum. Int. J. Syst. Evol. Microbiol. 2009; 59:1258.
- 🧍 The correct number of the type strain is JCM 14831, not JCM 14381 as cited in the paper by Tian et al. 2008. — Kudo T. Personal communication, 2009-02-02.
