摘　　要：报道了6种湖南新记录外来植物:翼茎阔苞菊Pluchea sagittalis(Lam.)Cabera,瘤梗甘薯Ipomoea lacunosa L.,长芒苋Amaranthus palmeri S.Watson,美丽月见草Oenothera speciosa Nutt.,假龙头花Physostegia virginiana(L.)Benth.和蒲苇Cortaderia selloana(Schult.&J.H.Schult.)Asch.&Graebn..其中翼茎阔苞菊、瘤梗甘薯、长芒苋和美丽月见草等4种为归化入侵植物新记录,假龙头花和蒲苇则为具潜在入侵威胁的外来植物.介绍了他们的生长习性、识别特征和繁殖特性等,对其危害、扩散性和入侵性进行了分析,提出了相应的管理策略.Six species of invasive plants in Hunan province were reported,in this work,as new records：Pluchea sagittalis（ Lam.） Cabera,Ipomoea lacunosa L.,Amaranthus palmeri S. Watson,Oenothera speciosa Nutt.,Physostegia virginiana（ L.） Benth. and Cortaderia selloana（ Schult. J. H. Schult.） Asch. Graebn.. Among them,Pluchea sagittalis（ Lam.） Cabera,Ipomoea lacunosa L.,Amaranthus palmeri S. Watson and Oenothera speciosa Nutt. are new recorded invasive plants in Hunan province for the first time. The other two species are potential invasive plants in Hunan province. This work also describes their growth habits,identifies characteristics and propagation properties,and then analyze and discuss their diffusivity and invasiveness. We put forward corresponding management strategies in the end.
