Asteraceae (Compositae), Türkiye’de en geniş bitki familyası olup 138 cins ve 1336 türle temsil edilir.Bu çalışmada Gamochaeta coarctata (Willd.) Kerguélen (Asteraceae) Türkiye Florası için yeni biryabancı tür olarak kaydedilmiştir. İstanbul-Kemerburgaz Kent Ormanı’nda 2021 yılı mayıs ayındayürüyüş yolu kenarında 250 den fazla bitkiden oluşan bir populasyon halinde görülmüştür. Bubilinmeyen bitkinin tespiti için bitkiden numune alınarak fotoğrafları çekilmiştir Araştırıldığında,bitkinin Türkiye Florasında yer almadığı görülmüş ve yapılan literatür taraması ile bitki Gamochaetacoarctata olarak teşhis edilerek Türkiye için yeni bir yabancı tür olarak teşhis edilmiştir. Bitkininalanda dağılımını belirlemek için arazide dolaşılmış ve farklı güzergahlardaki yürüyüş yollarınınkenarlarında, orman kenarında ve baraj gölü kenarındaki çayırda bitkinin yerleştiği gözlemlenmiştir.Türün bölgeye nasıl ve ne zaman geldiği bilinmemektedir. Hızlı yayılma kabiliyetinde olan bu yabancıtürün bulunduğu bölgede istilacı olma potansiyelinin yüksek olduğu düşünülmektedir.

Asteraceae is the largest plant family in Turkey and represented by 138 genera and 1336 species inTurkey. In this paper, Gamochaeta coarctata (Willd.) Kerguélen (Asteraceae) which is native inSouth America, is reported for the first time as a new alien species for Turkey (İstanbul). The plantwas noticed, in a population of more than 250 individuals on the side of walking path in May 2021.In order to identify this unfamiliar plant, a sample was taken from the plant and its photographswere taken. When researched, it was seen that the plant is not included in the Flora of Turkey andwith the literature review, the plant was identified as Gamochaeta coarctata which a new alienspecies for Turkey. In order to determine the area distribution of the plant, it was wandered aroundthe land and it was observed that the plant became established on the edges of the walking pathson different routes, on the forest edge and in the meadow by the dam lake. In this paper, thespecies was introduced with taxonomical and morphological features. Its ecological impact wasevaluated with potential risks also. The species can be considered in Turkey as an alien species andhave a rapid expansion potential, but further field investigations on this species are necessary toavoid its diffusion.
