广西外来种子植物新记录

摘要

报道了广西外来种子植物新记录5种,即银花苋、圭亚那笔花豆、墨苜蓿、盖裂果和红毛草,其中笔花豆属、墨苜蓿属、盖裂果属和糖蜜草属为广西新记录属.这些新记录植物均采自广西北部湾沿海地区,为广西滨海植物多样性研究提供了新资料,而随着外来物种在滨海地区逐渐增多,外来物种对当地生物多样性的影响值得关注.%Five exotic seed plants are reported as new records from Guangxi,including Gomphrena celosioides ,Stylosanthes guianensis ,Richardia scabra ,Mitracarpus hirtus ,Melinis repens. In addition,the genera Stylosanthes,Richardia, Mitracarpus and Melinis have not been previously recorded in Guangxi. All new recorded plants were discovered from Beibu Gulf coastal areas in Guangxi,which would provide information to the research of coastal plants biodiversity. With the increase of alien species,its impact on local biodiversity are also to concern.
