摘　　要：报道了天津植物新记录共计4种,分别是西部苋(Amaranthus rudis)、合被苋(A. polygonoides)、冠萼扁果葵(Anoda cristata)和小花山桃草(Gaura parviflora).这4种植物均原产北美,在中国及天津境内一定区域范围内形成了入侵态势.对其形态特征、在天津的地理分布和群落特征进行初步报道,为天津市植物区系研究提供了新资料,也为其动态监测和科学防治提供重要依据.Four exotic plant species of Tianjin were reported, including Amaranthus rudis, A. polygonoides, Anoda cristata and Gaura parviflora. The four species are all native to north America which have formed invasive populations in some areas in China. The morphological characteristics, distribution and population dynamics of these species in Tianjin were briefly demonstrated, which plays vital role to assist their dynamic monitoring and necessary control.
