# New Publication - Honoring Sabin Berthelot December 19, 2022 - [ News ](/news-categories/news) Senior Nomenclatural Registrar, Kanchi N. Gandhi, is one of the co-authors of a new publication in the *Journal of Plant Taxonomy and Geography* about the nomenclature of *Berthelotia* and its associated names. "[Honoring Sabin Berthelot: Nomenclature and botanical history of Berthelotia DC. (Asteraceae, Inuleae)](https://oaj.fupress.net/index.php/webbia/article/view/13735)" appears in the most recent volume of the journal, published Dec. 15, 2022. **Abstract** The genus *Berthelotia* DC. (presently a synonym of the accepted name *Pluchea* Cass.), Asteraceae, Inuleae has been regarded as comprising two species, *B. lanceolata* DC. and *B. sericea* (Nutt.) Rydb. It honors the French naturalist Sabin Berthelot (1794–1880) for his contribution to the studies of the flora and fauna of the Canary Islands. Under the leadership of Philip B. Webb (1793–1854), Berthelot co-authored the most important work pertinent to the natural history of this archipelago: *Histoire Naturelle des Îles Canaries*. The nomenclature of *Berthelotia* and its associated names are revisited here. The holotype of *Polypappus sericeus* Nutt. (K000974653) was located, and lectotypes were assigned to *B. lanceolata* (G00450458) and *B. lanceolata* var. *senegalensis* DC. (G00452584). Phylogenetic analyses based on nucleotide sequences of the nrDNA ITS were conducted focusing on members of what is known as the Clade J of the Inuleae. A well-supported clade (100% P.P.) that we have labeled as “Clade I” was uncovered, and it is composed of three species that belong to the *Pluchea indica* Clade plus *P. dioscoridis* and *P. ovalis*; but this lineage did not support a previous hypothesis to include *P. lanceolata*. The two species of *Berthelotia* did not form a monophyletic group and seem to be distantly related; furthermore, none of these two taxa is sister to *Tessaria*, a South American genus that has been suggested to be a close relative to *Berthelotia*. Ethnobotanical uses of *B. lanceolata* and *B. sericea* are reviewed. Naranjo, A. A., Pathirickal, R. R., Gandhi, K. N., Delprete, P. G., Baldini, R.
