石竹科植物2个中国新记录种

西藏南部地形较为复杂，植物资源丰富，物种多样性高。笔者在对西藏山南地区高山植物多样性调查过程中，经野外调查、采集标本、查阅植物志等相关资料及分类鉴定，结果发现，山南地区隆子县的无心菜属(Arenaria)球花福禄草［A. globiflora (Fenzl) Edgew. & Hook. f.］和错那县蝇子草属(Silene)的错那蝇子草(S. birgittae Bocquet)为中国新记录种。该报道一方面丰富了中国植物区系的内容，更新了国产石竹科植物资料，对中国西藏山南地区植物多样性的保护及研究具有一定意义。另一方面说明中国西藏山南地区的植物多样性调查仍存在许多调查薄弱地区，还需加强相关地区植物多样性调查工作。

New Records of Caryophyllaceae in China

Southern Tibet has a more complex topography, rich plant resources and high species diversity. For the survey of alpine plant diversity in the Shannan region of Tibet, field surveys, specimen collection, review of botanical histories and other relevant information and taxonomic identification were conducted. The results indicate that Arenaria globiflora (Fenzl) Edgew. & Hook. f. and Silene birgittae Bocquet are newly recorded species in China. This report, on the one hand, enriches the flora of China, updates the diversity of domestic Caryophyllaceae family, and has some significance for the conservation and study of plant diversity in the Shannan region of Tibet, China. On the other hand, it shows that plant diversity surveys in some areas of Shannan, Tibet, China are still inadequate and there are still many survey weak areas, which need to strengthen plant diversity surveys.
