| 摘要: |
| 花部形态是马铃苣苔属属下划分和种间界定的关键性状,缺乏花器官的描述直接导致了一些存疑物种的存在。网叶马铃苣苔(Oreocharis rhytidophylla C. Y. Wu ex H. W. Li)自1956年最后被采集到并于1983年发表,由于没有花的特征,在《中国植物志》《中国苦苣苔科植物》和Flora of China均存疑,但该种在随后的60余年间再无相关的采集记录。作者经过多年的跟踪调查,于2017年在其模式产地重新发现并采集了带花的凭证标本。该文作者根据已经采集到的具花标本,确定这个种是个自然种,并基于新收集到的材料,补充描述了花的形态特征。网叶马铃苣苔的重新发现,为探索其系统位置提供了重要的依据。 |

| Abstract: |
| Flower morphology is a key trait for sub-division and inter-species definition of genus Oreocharis. O. rhytidophylla C. Y. Wu ex H. W. Li was last collected in 1956 and published in 1983, and the species has no relevant collection records for the next 60 years. Due to the lack of flower morphology, there are doubts in Flora of Reipublicae Popularis Sinicae, Plants of Gesneriaceae in China and Flora of China. After years of follow-up investigation, Oreocharis rhytidophylla C. Y. Wu ex H. W. Li was rediscovered in 2017 in its type locality. Due to the availability of the flowers during the rediscovery, we confirmed that the species should be considered as a natural species instead of doubtful one. The floral morphology of O. rhytidophylla C. Y. Wu ex H. W. Li was supplemented based on the recent collections and photos. Its rediscovery provides an opportunity to explore its systematic position in the context of phylogeny in the future. |
