摘要: 2022—2023年在新疆各地的野外实地考察过程中,发现3种新疆未见文献报道和标本记录的菊科(Asteraceae)植物,通过形态分类鉴定和文献查证,确定其为新疆新记录种和外来有害杂草。分别为小花鬼针草(Bidens parvifloraWilld.)、婆婆针(Bidens bipinnataL.)、钻叶紫菀\[Symphyotrichum subulatum(Michx.) G. L. Nesom\]。对其形态特征、在新疆的地理分布和传播扩散特点进行介绍。新分布的发现为新疆菊科植物区系和物种多样性研究以及外来有害杂草的监测防控提供新依据。凭证标本均收藏于石河子大学植物标本馆(SHI)。

Abstract: During the field in 2022-2023, three species of Compositae, which had not been reported in Xinjiang, were discovered, and identified them as newly recorded species and exotic noxious weeds in Xinjiang by morphological classification and literature verification. They wereBidens parvifloraWilld.,Bidens bipinnataL. andSymphyotrichum subulatum(Michx.) G. L. Nesom. In this study, the morphological characteristics, geographic distribution and dispersal characteristics of these newly recorded species in Xinjiang were described. The discovery of the new distribution provided a new basis for the study of Compositae Flora and species diversity and the monitoring and control of exotic harmful weeds in Xinjiang. The voucher specimens are deposited at the Herbarium of Shihezi University (SHI).

Key words: Xinjiang, Compositae, newly record species, exotic weeds, invasive plants
