| 摘要: |
| 重庆地处川东-鄂西地区的核心地带，是中国植物多样性研究热点地区之一，摸清重庆被子植物资源本底，对重庆植物资源保护与利用具有重要意义。本研究团队通过形态观察、解剖以及与现有标本和文献进行比较，对重庆四面山植物标本进行整理。确定了重庆桔梗科(Campanulaceae)1新记录属——同钟花属(Homocodon D.Y.Hong)，以及5新记录种：同钟花[H.brevipes(Hemsley) D.Y.Hong]、湖南杜鹃(Rhododendron hunanenseChun ex Tam)、伞花落地梅(Lysimachia sciadanthaC.Y.Wu)、河边绶草(Spiranthes suniiBoufford & Wen H.Zhang)和毛叶鼠李(Rhamnus henryiC.K.Schneider)，其中4种为我国特有分类群。前述结果说明完善重庆及其周边区域植物种类多样性基础数据还需深入野外考察和对现有标本、历史文献进行整理。 |

| Abstract: |
| Chongqing is located in the core area of eastern Sichuan and western Hubei. It is one of the hot spots of plant diversity research in China. It is of great significance to find out the background of angiosperm resources in Chongqing for the protection and utilization of plant resources in Chongqing.This research team sorted out the plant specimens of Simian Mountain in Chongqing through morphological observation,anatomy and comparison with existing specimens and literature.Homocodon D.Y.Hong, a newly recorded genus of Campanulaceae in Chongqing, was identified. As well as 5 new records:H.brevipes (Hemsley) D.Y.Hong,Rhododendron hunanense Chun ex Tam,Lysimachia sciadantha C.Y.Wu,Spiranthes sunii Boufford & Wen H.Zhang and Rhamnus henryi C.K.Schneider.Four of them are endemic to China.It shows that the improvement of the basic data of plant species diversity in Chongqing and its surrounding areas needs in-depth field investigation and collation of existing specimens and historical documents. |
