| 摘要: |
| 该文报道了中国大陆新发现的两种归化植物:菊科的白花猫儿菊 [Hypochaeris albiflora (Kuntze)Azevêdo-Gonç. & Matzenb.]和茄科的黄果龙葵(Solanum diphyllum Linn.)。白花猫儿菊原产于南美洲,在中国的云南省昆明市盘龙区发现归化,其与同属种类的区别在于基生叶全缘或有尖齿,有时羽状浅裂至深裂,茎生叶线形,头状花序圆筒形或狭钟状,小花白色,瘦果有4棱。黄果龙葵原产于墨西哥和中美洲,在中国的云南省勐腊县发现归化,其主要识别特征为多年生常绿小灌木,上部叶常双生,大小显著不相等,成熟浆果呈亮黄色。此外,该文还简要评估了这两种归化植物的危害和入侵风险。 |

| Abstract: |
| Two newly naturalized plants, namely Hypochaeris albiflora (Kuntze)Azevêdo-Gonç. & Matzenb.(Asteraceae)and Solanum diphyllum Linn.(Solanaceae), were first recorded in mainland China. Hypochaeris albiflora is native to South America, and has become locally naturalized in Panlong District, Yunnan Province, Southwest China. In genus Hypochaeris, H. albiflora is characterized by its basal leaves entire or dentate, sometimes pinnately lobed to deeply lobed, cauline leaves linear, capitula cylindrical or narrowly campanulate, florets white and achene with four ribs. Solanum diphyllum is native to the Mexico and Central America, it is now found naturalized in Mengla County, Yunnan Province, Southwest China. S. diphyllum is a perennial evergreen shrub and characterized by its upper leaves usually arranged in pairs on each node and unequal in size, mature fruits yellow. In additon, the potential harm and invasive risks of these two naturalized plants are briefly assessed as well. |
