| 摘要: |
| 原唇柱苣苔属(Chirita Buch.-Ham. ex D. Don)为一个人为界定的属, 2011年在分子系统学研究的基础上对该属及其近缘属开展了系统发育重建工作,其中绝大部分的原唇柱苣苔属唇柱苣苔组(Sect. Gibbosaccus C. B. Clark)的物种被并入了广义报春苣苔属(Primulina Hance)。然而,由于历史原因和早期经典分类学在研究方法上的局限性以及对现报春苣苔属部分物种的营养器官与生殖器官的认知不够,该属下一些物种的分类仍存在一些问题,亟待深入研究。比如,在对中国和越南分布的苦苣苔科植物开展研究的过程中,作者发现两个报春苣苔属的物种——广布于中国西南和华南直至中南半岛中部的钟冠报春苣苔[Primulina swinglei(Merr.)Mich. Möller & A. Weber]命名人和原被认为是中国与广西特有种的疏花报春苣苔[P. laxiflora(W. T. Wang)Yin. Z. Wang]之间的鉴定存在分类学问题,需要进一步厘清两者之间的关系。该文对这两个物种进行了形态比较,同时通过对这两种植物的原始描述对比、植物标本检查、栽培观察以及野外实地观察,确定疏花报春苣苔是钟冠报春苣苔的异名。此外,还明确了钟冠报春苣苔的后选指定模式标本。 |

| 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. However, due to historical reasons, 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 studied, there are still some problems in the classification of some species of this genus, which need to be further studied. For example, in the process of studying Gesneriaceae plants distributed in China and Vietnam, we found that there are taxonomic problems in the identification of two species of Primulina: Primulina swinglei(Merr.)Mich. Möller & A. Weber, which is widely distributed from Southwest China to the middle of Indochina Peninsula, and P. laxiflora(W. T. Wang)Yin Z. Wang, 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 paper, the morphological comparison of the two species was carried out. At the same time, through the original description comparison, plant specimen examination, cultivation observation and field observation of the two plants, we determined that P. laxiflora is the synonym of P. swinglei. In addition, the lectotype of P. swinglei is also designated here to confirm the taxonomic status of the species. |
