摘　　要：报道广东菊科一新归化属——伏金腰箭属Calyptocarpus Less.。该属的伏金腰箭C. vialis Less.原产于美国南部、墨西哥和古巴,在我国台湾、云南和广西以及印度尼西亚爪哇岛、大洋洲、印度、非洲等地区已归化。最近在广州市车陂涌发现该种大量的归化居群,且生长旺盛并排斥其他原生草本植物,具有明显的入侵性,应引起相关部门重视。伏金腰箭茎匍匐,舌状花瘦果边缘无翅,与管状花瘦果同型,托片先端锐尖,易与金腰箭Synedrella nodiflora (L.) Gaertn.区别。凭证标本保存于中国科学院华南植物园标本馆(IBSC)。This paper reported a newly naturalized genus of Asteraceae,Calyptocarpus Less.in Guangdong.C.vialis Less.is native to the southern United States,Mexico and Cuba,and was previously reported to be naturalized in China(Taiwan,Yunnan and Guangxi),Indonesia(Java),Oceania,India and Africa.Many populations of this invasive species were discovered in Chebei Chong,Guangzhou.It grows vigorously and tends to take over the habitat of other native herbaceous plants,which seems to be an invasive species and should attract the attention of relevant departments.Calyptocarpus vialis is similar to Synedrella nodiflora(L.)Gaertn.,but markedly differs by having prostrate stems,homogeneous achenes with wingless ray ones,and palea with an acute apex.The vouchers are deposited in the herbarium of South China Botanical Garden,Chinese Academy of Sciences(IBSC).
