Abstract

Paphiopedilum helenae, a member of the genus Paphiopedilum, Orchidaceae, is an endangered species. This study used molecular data with 29 newly sequenced samples of P. helenae in Vietnam to investigate its phylogeny. The results of molecular data analysis strongly support that Paphiopedilum is a monophyletic group. Four subgenera were recorded within Paphiopedilum, namely Parvisepalum, Brachypetalum, Megastaminodium and Paphiopedilum. Compared with previous studies, the results of this study suggest that the population of P. helenae was recorded as monophyletic in the section Paphiopedilum. The individuals of the species are concentrated in a group, especially the individuals of P. helenae in Vietnam are not placed together but are mixed with other individuals of China. These results show that the genetics of Paphiopedilum helenae populations in Vietnam and China are highly conservative, and there are genetic variations in this population; however, these current genetic variations are not significant for taxonomic arrangement and phylogeny.
