       Abstract: The former Chirita Buch. ̄Ham. ex D. Don is a human ̄defined genus. Phylogenetic reconstruction of this
       genus and its related genera was carried out on the basis of molecular systematics research in 2011. Most of the species of
       Sect. Gibbosaccus C.B. Clark were incorporated into Primulina Hance. Howeverꎬ due to historical reasonsꎬ the limitations
       of early classical taxonomy in research methods and the understanding of vegetative organs and reproductive organs of
       some species of former Chirita need to be further studiedꎬ there are still some problems in the classification of some
       species of this genusꎬ which need to be further studied. For exampleꎬ in the process of studying Gesneriaceae plants
       distributed in China and Vietnamꎬ we found that there are taxonomic problems in the identification of two species of
       Primulina: Primulina swinglei (Merr.) Mich. Möller & A. Weberꎬ which is widely distributed from Southwest China to
       the middle of Indochina Peninsulaꎬ and P. laxiflora (W. T. Wang) Yin Z. Wangꎬ which was originally considered to be
       endemic to China and Guangxi. Further clarification is needed to clarify the relationship between the two species. In this
       paperꎬ the morphological comparison of the two species was carried out. At the same timeꎬ through the original
       description comparisonꎬ plant specimen examinationꎬ cultivation observation and field observation of the two plantsꎬ we
       determined that P. laxiflora is the synonym of P. swinglei. In additionꎬ the lectotype of P. swinglei is also designated here
       to confirm the taxonomic status of the species.
