Abstract:

The genus Camellia comprises a vast number of species that are widely distributed across various regions. The frequent inter-specific hybridization results in,controversial and unstable taxonomy and systematics among different species,which also poses a greater challenge for infrageneric classification within Camellia. Based on morphological features,Sealy,Chang Hongda,and Min Tianlu have established three classification systems for species in the genus. However they hold different opinions on the taxonomic significance of each character. This paper presents a comprehensive overview of the classification and phylogenetic research progress on the Camellia genus from a global perspectives. Pertinent research on phylogeny reconstruction of Camellia genus based on various marker types were summarized,appraise the merits and demerits of these markers in elucidating phylogenetic relationships,and propose future research directions to address current classification issues. The paper provides valuable insights into reconstructing the systematic relationship within the Camellia genus and resolving classification disputes.
