摘要: |
【目的】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,摸清本底,对重庆市植物资源保护与利用具有重要意义。【方法】通过野外调查、标本采集和文献查阅,进行了分类鉴定。【结果】确定了重庆桔梗科1新记录属—同钟花属(Homocodon)和5新记录种,即同钟花(H. brevipes)、湖南杜鹃(Rhododendron hunanense)、伞花落地梅(Lysimachia sciadantha)、河边绶草(Spiranthes sunii)、毛叶鼠李(Rhamnus henryi),它们均是我国特有分类群。【结论】完善重庆及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和历史文献整理。 |

Abstract: |
【Purposes】Chongqing is located in the core area of E Sichuan-W Hubei, one of the plant diversity hot-spots in China. A thorough inventory of plant species will have vital importance for the protection and utilization of plant resources in Chongqing and adjacent regions. 【Methods】Specimens were collected when doing field investigations. And species were identified based on morphological comparisons and literature perusals. 【Findings】Homocodon (Campanulaceae) is confirmed to be a new generic record, with the species H. bervipes newly included in flora of Chongqing. Additional four new record species in Chongqing are Rhododendron hunanense (Ericaceae), Lysimachia sciadantha (Primulaceae), Spiranthes sunii (Orchidaceae), and Rhamnus henryi (Rhamnaceae). All the newly recorded taxa in Chongqing are Chinse endemics. 【Conclusions】It is supposed that further field works together with studies on available herbarium specimens and literature records are still essential to have a better understanding of the basic plant species data in Chongqing and adjacent regions. |
