六种山东省新记录植物

Six newly recorded plant species from Shandong Province

为了摸清山东省黄河、沂沭河、南四湖流域及潍坊等地区的植物资源和多样性现状,采用野外实地调查、采集标本和室内分类整理、解剖鉴定相结合的方法,对相关地区进行了全面详细的调查研究。结果表明,所研究地区共有维管植物1194种,隶属于155科587属。其中,6种为山东省地理分布新记录植物,即穗花香科科(Teucrium japonicum)、小叶地锦(Euphorbia heyneana)、光头稗(Echinochloa colona)、竹节菜(Commelina diffusa)、蚓果芥(Braya humilis)和羽叶鬼针草(Bidens maximowicziana),描述了其关键识别特征,探讨了其分布现状和应用价值。这些植物的发现,不仅丰富了山东植物资源和多样性的本底资料,而且对相关科属的系统分类、区系地理及分布规律的研究具有重要意义。

To ascertain the current status of plant resources and biodiversity in the Yellow River,Yishu River,Nansi Lake Basin and Weifang in Shandong Province,a comprehensive and detailed investigation was conducted by combining field investigation,specimen collection,indoor classification,and anatomical identification.The results identified 1194 species of vascular plants belonging to 587 genera and 155 families.Among these,6 species,namely Teucrium japonicum,Euphorbia heyneana,Echinochloa colona,Commelina diffusa,Braya humilis,and Bidens maximowicziana,were newly recorded in Shandong Province.The key identification characteristics of these species are described in this study,and the distribution status and application value are also discussed.The discovery of these plants not only enriches the background data of plant resources and plant diversity in Shandong,but also is significancant to the study of the systematic classification,floristic plant geography,and distribution patterns of related families and genera.
