Arrhenatherum elatius subsp. bulbosum (Poaceae): A New Alien Record for the Flora of Turkey

Abstract

Invasive alien species are one of the largest threats to global biodiversity together with social, environmental and economic problems. As well, they present significant threats to global agriculture especially in the regions with moderate temperature as in northeast Anatolia. Arrhenatherum elatius (L.) P. Beauv. ex J. Presl. & C. Presl. subsp. bulbosum (Willd.) Schübl. & Martens (Poaceae) was observed in farmlands, an invasive alien taxon in tea and hazelnut plantations, in Turkey where it was established in a new ecosystem, outside its natural range in SW Europe. In this article, this subspecies was reported as a new alien vascular plant taxon for the Flora of Turkey. At the base of its stems the adjacent nodes are swollen and form a chain of bulbs which characterize this taxon and differentiate it from other subspecies. New Turkish name and photographs of the new record are also presented in the article.

A New Invasive Plant Record For Flora of Turkey: Grindelia hirsutula Hook. & Arn.

“…Türkiye yaklaşık 92 familya ile 251 cinse ait 340 kadar istilacı bitki taksonunu florasında barındırmaktadır (Uludağ ve ark., 2017). Son on yılda, ülkemizin yerli türlerinden olmayan, egzotik, yabancı ot veya istilacı gibi isimlerle adlandırılan birçok bitki türü kaydının verildiği görülmektedir (Üremiş ve ark., 2014;Ekizoğlu, 2016;Hançerli ve ark., 2018;Fırat, 2018;Yıldırım ve ark., 2019;Terzioğlu, 2020;Terzioğlu ve Özkan, 2020;Karaer ve ark., 2020;Eker ve Tuzlacı, 2021;Yılmaz, 2021;Yazlık, 2021;Bozkurt, ve ark., 2021;Önen, ve ark., 2021;Tunçkol, 2022;Coşkunçelebi ve Terzioğlu, 2022;Sefalı ve Eroğlu, 2022;Asal ve ark., 2022). Kaydı verilen bu bitkiler için farklı araştırmacılar tarafından istilacı, egzotik ve yabancı ot terimleri birbirlerinin yerine kullanılmıştır.…”
