Six newly recorded plant species from Shandong Province
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 1 194 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.
