New Names and New Combinations of the Genera of Bambusa, Dinochloa and Guadua (Bambusaceae)

The subfamily Bambusoideae Luerss., belonging to the family Bambusaceae Burnett, is intricately intertwined with human production and daily life, exerting a profound influence on culture as well. The distinctive characteristics of the subfamily, such as culm, rhizome, branch, and culm sheath, have traditionally been employed in taxonomic classification, which requires further research to validate from a scientific perspective. Using the minimum criterion PHS (phylogenetic similarity) ≤ 0.928 (inter genera) for genus classification by CPCG (chloroplast complete genomes) of Fructophyta D.L.Fu & H.Fu, total 22 synonyms of three genera of Bambusa Schreb., Dinochloa Büse and Guadua Kunth within the subfamily, have been identified, 15 current synonyms of the genus Bambusa Schreb. including Bonia Balansa, Dendrocalamus Nees, Gigantochloa Kurz ex Munro, Holttumochloa K.M.Wong, Kinabaluchloa K.M.Wong, Maclurochloa K.M.Wong, Melocalamus Benth., Neomicrocalamus Keng f., Oreobambos K.Schum., Oxytenanthera Munro, Phuphanochloa Sungkaew & Teerawat., Soejatmia K.M.Wong, Temochloa S.Dransf., Thyrsostachys Gamble and Vietnamosasa T.Q.Nguyen, 3 current synonyms of the genus Dinochloa Büse being Cyrtochloa S.Dransf., Neololeba Widjaja and Sphaerobambos S.Dransf., and 4 current synonyms of the genus Guadua Kunth being Apoclada McClure, Eremocaulon Soderstr. & Londoño, Olmeca Soderstr. and Otatea (McClure & E.W.Sm.) C.E.Calderón & Soderstr.. Additionally, 27 new specific names such as Bambusa bifloscula D.L.Fu and Dinochloa hirta D.L.Fu, along with 184 new specific combinations like Bambusa achmadii (Widjaja) D.L.Fu, Dinochloa acutiflora (Munro) D.L.Fu and Guadua acuminata (Munro) D.L.Fu have been scientifically and validly published. These publications will scientifically address the taxonomic nomenclature confusion and establish a robust foundation for the research of evolutionary system within the family Bambusaceae Burnett.
