摘　　要：报道了3种广西新记录归化植物,即苏里南莎草(Cyperus surinamensis)、香膏萼距花(Cuphea balsamona)和文定果(Muntingia calabura),为广西外来入侵植物的预防和控制提供科学依据。以这3种归化植物为研究对象,通过野外调查,分析其发生入侵的可能性。结合文献,介绍3种归化植物的形态特征、地理分布、生长习性和繁殖特性。3种植物均已在广西自然生境中建立种群;香膏萼距花是广西新记录入侵植物,苏里南莎草具有潜在入侵性,文定果发生入侵的可能性小。这3种外来植物将来可能会扩散到更多地方,应加强防范,密切关注其野外种群的发展趋势,定期开展调查和监测。Three newly recorded naturalized plants in Guangxi were reported, which were Cyperus surinamensis, Cuphea balsamona and Muntingia calabura, which could provide scientific basis for prevention and control of invasive alien plants in Guangxi. Taking these three naturalized plants as research objects, possibility of invasion were analyzed through field investigation. Combined with literatures, morphological characteristics, geographical distribution, growth habits and reproductive characteristics of three species were introduced. Popultions of all three species have been established in natural habitats of Guangxi. C. balsamona was a newly recorded invasive plant in Guangxi. C. surinanensis had potential invasiveness, and M. calabura was less likely to become an invasive species. These three alien plants might spread to more places in the future. Prevention should be strengthened, development trend of wild population musts be paid more attention and regular investigation and monitoring could be carried out.
