Contributions to Turkish Flora: Taxonomic and distributional notes on the poorly known Noccaea (Brassicaceae) species

Abstract

Herein the taxonomical status of some poorly known Noccaea (Brassicaceae) species is revised. Moreover, the morphological, distributional and ecological properties of these species are updated. Some overlooked species in Turkey such as Noccaea versicolor and N. aptera are recollected and their descriptions emended and discussed. N. huber-morathii is also recollected from its type locality after its first collection. The description and distribution of N. huber-morathii are also updated. New distribution areas for N. tatiaae and N. aghrica, which have been insufficiently known species in Turkey, are also given.

Structural characterization of ITS2 and CBC species concept applications in the tribe Coluteocarpeae (Brassicaceae)

“…On the basis of Torres-Suárez (2014) findings, only one CBC, between the outgroup and the tribe Coluteocarpeae, indicates that Noccaea sensu Al-Shehbaz (2014) was more acceptable despite of some studies (Ali et al, 2016a;2016b;Karaismailoğlu and Erol, 2018; https://brassibase.cos.uni-heidelberg.de/, accessed 27 August 2019) which disagree with generic delimitation of Al-Shehbaz (2014). This finding is also supported by previous studies (German, 2017;Özgişi, 2018a;Özgişi et al, 2018b;Güzel et al, 2018;Özüdoğru and German, 2018;Özüdoğru et al, 2019) which consider that Noccaea sensu Al-Shehbaz (2014) is more acceptable.…”

“…The tribal classification of Al-Shehbaz (2012) was accepted by some researchers (Ali et al, 2016a;German, 2017;Özgişi et al, 2018a;Özgişi et al, 2018b; https://brassibase.cos.uni-heidelberg.de/, accessed 27 August 2019). However, the generic classification of Coluteocarpeae remains controversial.…”

“…However, the generic classification of Coluteocarpeae remains controversial. While some researchers (Özgişi et al, 2018a;Özgişi et al, 2018b;Güzel et al, 2018;Özüdoğru, 2018) have accepted the concept of Al-Shehbaz (2014), others (Ali et al, 2016a;2016b;Karaismailoğlu and Erol, 2018;; https://brassibase. cos.uni-heidelberg.de/, accessed 27 August 2019) have chosen to follow different concepts.…”

“…In addition to the debates (Greuter and Raus, 1983;Greuter et al, 1986;Artelari, 2002;Aytaç et al, 2006;Ali et al, 2016a;German, 2017;Özgişi et al, 2018a;Özgişi et al, 2018b;Karaismailoğlu and Erol, 2018) regarding the generic concept by Meyer (1973;1979), variations among the morphological features that were used for species delimitation resulted in misevaluation of the species (Özgişi, 2018a). Because of these variations, the morphology-based keys to identify specimens, which was proposed by Meyer (1973;1979; and Herein, the secondary structure properties of ITS2 were tested for the tribe Coluteocarpeae, whose generic delimitation has been debated.…”

Comparative anatomy and pollen morphology of two endemic Noccaea species (Brassicaceae) and their taxonomic significance

“…Genus Noccaea Moench is a systematically problematic genera within the Brassicaceae family, and discussions about the generic circumscription of this genus still continue (Özüdoğru, 2017). Just because of the problems related to the systematics of the genus, several taxonomic studies have been carried out on the classification of the Noccaea (Al-Shehbaz, 2012;Al-Shehbaz, 2014;Al-Shehbaz et al, 2006;Özgişi et al, 2018a). In these studies, researchers mainly used morphological characters such as flower characteristics (leaves and fruit shapes) to constrain the generic circumscription of Noccaea species (Özgişi et al, 2020).…”
