中国口岸首次监测外来杂草——胡氏苘麻

Abutilon hulseanum(Torrey & A. Gray) Torrey ex Baker f.—an alien weed first monitored at China port

胡氏苘麻为多年生草本或亚灌木植物,原产北美洲,中国尚未有分布。2016年,泰州口岸在国门生物安全监测中首次发现该种外来杂草。本文根据监测到的胡氏苘麻及栽培植株,对其形态特征进行详细描述;并根据资料,对其分类地位、地理分布、生态及与近似种的主要区别进行了描述。在此基础上,分析口岸苘麻属杂草截获情况,提出胡氏苘麻的检疫鉴定和研究建议。

Abutilon hulseanum（Torrey A. Gray） Torrey ex Baker f. is a perennial subshrubs native to North America,and there is no distribution in China. It was first found at Taizhou port during routine investigation required by National Biosafety Monitoring Program. The classification,geographical distribution,morphological characteristics,ecology of it and main differences with its similar species were described based on collected speciman and reference documentation. The interception situation of Abutilon spp. at China ports was analyzed,and some suggestions were proposed,which might provide reference for its identification and research.
