'Centaurea akcadaghensis' and 'C. ermenekensis' (Asteracaeae), two new species from Turkey

Abstract

Two new species of Centaurea subg. Cyanus (Asteraceae) from Anatolia are described and illustrated. Centaurea akcadaghensis Uysal & Şirin occurs on open Quercus forest of Levent Canyon (Akçadağ-Malatya) and differs from C. matthiolifolia Boiss. mainly in stem, leaves, central flowers and achenes measures. Centaurea ermenekensis Şirin & Uysal is restricted to steppes of Göktepe (Ermenek-Karaman) and can be distinguished from C. reuteriana Boiss. by the stem, number of capitula, involucre and median appendages measures.

“…2016;Uysal & Hamzaoğlu 2017;Şirin vd. 2019;2020), diğer nedenler ise, düşük maliyetli ve kolay yetiştirilebilir olmaları, tohumlarının çimlenmesinin hızlı olması, görsel özelliklerinin kısa zamanda sonuç vermesi ve etkilerini uzun süre göstermeleri, yaşam sürelerinin yıllık/çok yıllık olması nedeniyle genellikle yetişme ortamı istekleri açısından toleranslı olmaları, hastalık ve zararlılara karşı dayanıklı olmaları ve bir takım mekanik etkilere karşı direnç göstermeleridir.…”

Centaurea kirikkalensis (Asteraceae), a new species from Turkey

“…According to Uysal (2012), Centaurea has 195 taxa in Turkey. Since then, 17 new taxa and three new records from Turkey have been published (Yıldırımlı 2012, Köse and Alan 2013, Bancheva et al 2014, Duran et al 2014, Bancheva and Kaya 2015, Bona 2015a, 2016, Negaresh et al 2015, Yüzbaşıoğlu et al 2015, Kültür et al 2016, Pınar 2016, Uysal et al 2016, 2017, Uysal and Hamzaoğlu 2017, Behçet et al 2017, Armağan and Uysal 2018, Negaresh and Rahiminejad 2018, Yıldırımlı 2018, Şirin et al 2019, 2020, Hamzaoğlu and Koç 2020). Thus, this genus currently comprises 218 taxa in Turkey, 130 of which are endemic so the endemism rate is about 60% (Hamzaoğlu and Koç 2020).…”

A new species of Centaurea (Asteraceae) from northern Turkey

“…In Flora of Turkey and the East Aegean Islands, 172 species (including six imperfectly known ones) of Centaurea were recognized (Wagenitz 1975). Currently, with the last additions, Centaurea is represented by 206 taxa in Turkey (Köse et al 2010, Uysal 2012, Bona 2015, Yüzbaşıoğlu et al 2015, Kültür et al 2016, Uysal and Hamzaoğlu 2016, Uysal et al 2016a, 2016b, 2017, Behçet et al 2017, Armağan and Uysal 2018, Şirin et al 2019, 2020). In the light of these data, the endemism rate of this genus in Turkey has reached 64%.…”
