摘　　要：近年来本团队对新疆北疆和东疆地区的本土与外来杂草进行了野外实地调查,在胡杨河市和哈密市发现鳢肠(Eclipta prostrata L.)、在哈密市发现石胡荽(Centipeda minima(Linn.)A.Br.et Aschers.)、在伊犁地区发现抱茎棘头花(Acanthocephalus amplexifolius Kar.et Kir.)等菊科3种新记录植物,利用《新疆植物志》、Flora of China、《中国植物志》等相关资料和形态分类学研究确定其为新疆新记录种和中国新记录种。本研究发现菊科鳢肠(Eclipta prostrata L.)、石胡荽(Centipeda minima(L.)A.Br.et Aschers.)2种为新疆新记录种和外来入侵植物;抱茎棘头花(Acanthocephalus amplexifolius Kar.et Kir.)为中国和新疆本土新记录种;鳢肠属(Eclipta L.)和石胡荽属(Centipeda Lour.)为新疆新记录属。鳢肠在胡杨河市车排子垦区、哈密市伊州区等地均有分布;石胡荽在哈密市伊州区有发现;抱茎棘头花在伊犁霍城县有自然分布。这些新记录植物的发现对新疆菊科植物区系和物种多样性研究具有重要意义,也为该新记录属种的地理分布研究、外来入侵杂草的有效监测与科学防控提供了理论依据和参考资料。凭证标本均收藏于石河子大学植物标本馆(SHI)。In recent years,three new records of Compositae,including Eclipta prostrata L.,Centipeda minima(Linn.)A.Br.et Aschers.,and Acanthocephalus amplexifolius Kar.et Kir.,were found in Huyanghe City and Hami City.Based on the relevant data of Xinjianggensis Flora and Flora of China and morphological taxonomic studies,they were confirmed as new record species in Xinjiang or new record species in China.In this study,Eclipta prostrata L.and Centipeda minima(L.).A.Br.et Aschers.are new record species in Xinjiang and exotic invasive weeds,Acanthocephalus amplexifolius Kar.et Kir.is a new record in China and Xinjiang;Eclipta L.and Centipeda Lour.newly recorded genera in Xinjiang.Eclipta prostrata is currently distributed in Chepaizi Reclamation District of Huyanghe City and Yizhou District of Hami City and other places;Centipeda minima is found in Yizhou district of Hami City;The species of Acanthocephalus amplexifolius Kar.et Kir.are naturally distributed in Huocheng County of Yili City.The discovery of these newly recorded plants is of great significance to the study of Compositae flora and species diversity in Xinjiang,and also provides a theoretical basis and reference for the study of geographical distribution of newly recorded genera and species,effective monitoring and scientific control of alien invasive weeds.The voucher specimens are deposited in the Botanical Herbarium of Shihezi University(SHI).
