... Meyer's revision (1973) was a successful first step, difficulties in its implementation prevented its wide- scale utilization (Al-Shehbaz 2014). In Meyer's revisions (Meyer 2003(Meyer , 2006), almost all of the identification keys for different genera were based on fruit characters such as wings, apical notch, horns, etc., however, our investigations based on comprehensive field studies and observations showed that fruit can be extremely variable even within individuals of a species. Therefore, a precise decision about a species status' should be based on multiple accessions (if available) and different fruit stages. The most striking example for this case is N. caerulescens (J. Presl & C.Presl (1819: 133)) Meyer (1973: 463). This species is widespread in Europe, but it has too many synonyms (Meyer 2006, Al-Shehbaz 2014) because of its variable characters. One of the most taxonomically problematic Turkish Noccaea species is N. ochroleuca (Boissier & Heldreich 1849:39) Meyer (1973. Although in the first volume of Flora of Turkey many accessions of this species were given by Hedge (1965), Meyer (2006) argued that this species occurs only in the province of Isparta (type locality). Contrary to Meyer (2006), Anč ev (2007) presented N. ochroleuca as a native plant of Bulgaria. An interesting specimen was collected from Çanakkale (Fig. 2) by Sintenis (Edinburgh herbarium number E00059943) and treated as Thlaspi ochroleucum Boissier & Heldreich (1849: 326) in Flora of Turkey, but Meyer (1973) identified this specimen as N. versicolor in his revision because of its style length, ovule numbers and petal colour. According to Meyer (2006), N. ochroleuca differs from N. versicolor by having 4 seeds (vs. 6) per locule, larger basal leaves and whiter petals. Although Hedge (1965) could not specify the relationships of N. ochroleuca, Meyer (2006) argued that N. ochroleuca, N. versicolor and N. lutescens (Velen.) Meyer (1973: 462) are closely related ...

... most remarkable difference in the comparison of our specimens with the description of N. versicolor was the presence of an apical notch. Meyer misevaluated the position of the style in his account because of the lack of mature fruits. Our field observations clearly showed that the fruit shape of Noccaea species can dramatically change when the fruit becomes fully ripe. In the case of N. versicolor, mature fruit has a very distinct apical notch, whereas immature fruit does not, as in the case of the type specimen (Fig. ...

Noccaea anatolica ssp. Nov. (Brassicaceae) is described and illustrated as a new species from Van Province in eastern Anatolia, Turkey. Diagnostic morphological characteristics, a full description, detailed illustrations, and a distribution map are provided. It is morphologically similar to Noccaea sintenisii and Noccaea valerianoides but easily differs from these species by its fruit shape, seed characters, and basal leaf shape and also general habit.
... 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). ...
This study was conducted for extensive and systemic investigation of anatomical, palynological and seed morphological properties of two endemic Noccaea species, naturally growing in Turkey. Independent sample T-test and box plot were carried out using quantitative characters of the studied species. The anatomical results showed that the species had similar characteristics, though there were significant differences in root cortex cells and trachea; stem epidermis, cortex cell and endodermis; leaf upper and lower epidermis, lower cuticle, mesophyll and palisade parenchyma. Pollen grains of two endemic species were observed as radially symmetric, isopolar, with tricolpate aperture, prolate pollen shape and had small size. Pollen surface ornamentation was micro-reticulate in both species. Considering palynological characters, equatorial axis, AMB exine and intine have taxonomic importance. Seeds of N. birolmutlui were ovate to orbicular in shape and orange-brown in color, with colliculate ornamentation; however, the seeds of N. camlikensis were ovate to oblong in shape and brown and shiny in color, with colliculate-reticulate ornamentation.

Because of these variations, the morphology-based keys to identify specimens, which was proposed by Meyer (1973;1979; and Al-Shehbaz (2014) have been inadequate in some cases (i.e. for distinguishing N. densiflora (Boiss. ...
This study investigates the seed and fruit anatomy and micromorphology of five pennycress taxa (Thlaspi L. sensu lato) from Turkey, some of which have not been previously investigated. Systematic work in this group suffers from a lack of comprehensive anatomical and micromorphological data, especially for narrowly endemic species. We find that seed surface structure is taxonomically more useful than seed coat anatomy in Thlaspi s. lat., but despite this, it remains understudied. Our results indicate that the most useful anatomical characters are seed-epidermis cell shape and the presence of mucilage cells. As for micromorphology, seed periclinal walls and cell shape were most significant. Thlaspi ceratocarpon Murray, the only taxa remaining in Thlaspi sensu stricto, was unique among these taxa both anatomically and micromorphologically. It notably differs from Thlaspi alliaceum L., according to our results, corroborating recent studies that placed the latter into Mummenhoffia Esmailbegi & Al-Shehbaz. Our PCoA analysis resulted in a close grouping of T. jaubertii Hedge, T. crassum P.H. Davis and T. cilicicum (Boiss) Hayek, three species that have been moved to Noccaea Moench, based on molecular evidence. We discuss the fragmentation of Thlaspi s. lat. into smaller genera in the context of broader trends in plant systematics.
The accurate identification of an organism is the basis of all biological disciplines. Although there have been many different species concepts and methods proposed, researchers generally choose the most appropriate concept according to their interests. However, each species concept has both advantages and disadvantages. In such cases, an integrated concept based on evidence obtained from different species concepts and methods is suitable for the accurate delimitation of a species. The biggest dilemma of integrated species delimitation methods is the inconsistency between species concepts and methods. Herein, the congruency of the different concepts and methods was tested to reveal the relationship of the Noccaea densiflora species complex. nrITS, chloroplast trnL-F, and trnQ-5'rps16 regions were used for species delimitation using the multispecies coalescent model (MSC) as implemented in two developed Bayesian Methods. ITS and trnL-F regions were also used for TCS haplotype network analyses. In addition to morphological measurements from different populations and vouchers, specific bioclimatic data values were also used for the principal component analysis. Based on all of the analyses, it was determined that only one population of N. densiflora and and one of N. microstyla were clearly distinct, whereas the rest of the specimens remain taxonomically uncertain.
Yaklaşık 75 taksonla temsil edilen Thlaspi L. cinsinin sistematiği, 351 Brassicaceae cinsi arasında en tartışmalı olanlardan biridir. Schulz'dan etkilenen Meyer, Thlaspi cinsini 11 farklı cinse ayırmıştır. Bu cinslerden biri olan Thlaspicerasas F. K. Meyer, daha sonra Noccaea cinsi altında bir tür kompleksi olarak kabul edilmiştir. Bu tür kompleksi dokuzu Türkeye’ye endemik olan toplam 11 türden oluşmaktadır. Sınıflandırmada sıklıkla kullanılan meyve karakterindeki konvergensin ve varyasyonun varlığı toplam tür sayısı hakkında tartışmalara neden olmaktadır. Bu çalışmada Bayesian İstatistiksel Metoduna dayalı BPP tür sınırlandırma programı tür sınırlandırma çalışmaları için kullanılmıştır. Çekirdek DNA’sına ait Internal Transcribed Spacers (ITS) ile plastid DNA’sına ait trnL-F ve trnQ-5'rps16 moleküler belirteçleri kullanılarak tür sınırlandırma çalışmaları üç farklı senaryo (Küçük, orta ve büyük atasal popülasyon büyüklüğü) altında incelenmiştir. Ayrıca biyoklimatik veriler (19 biyoklimatik verinin yanı sıra aylık en düşük, ortalama, en yüksek sıcaklık değerleri ve aylık ortalama yağış miktarları) kullanılarak türlerin biyoklimatik tercihleri tespit edilmiştir. Tür sınırlandırma çalışmalarında küçük atasal popülasyon büyüklüğü modeli altında gerçekleştirilen çalışmalara göre 0.63 ardıl olasılık değeri ile tür kompleksi altı türden oluşmaktadır. Orta atasal popülasyon büyüklüğü modeline göre ise 0.78 ardıl olasılık değeri ile üç farklı türün varlığı tespit edilmiştir. Büyük atasal popülasyon büyüklüğü modeli ise 1.00 ardıl olasılık değeri ile kompleksin sadece tek bir türden oluştuğunu göstermiştir. Türlerin biyoklimatik isteklerini belirlemeye yönelik çalışmada ise Noccaea huber-morathii (F.K.Meyer) Al-Shehbaz türünün daha soğuk ve nemli alanları tercih ederken Noccaea meyerii (F.K.Meyer) Al-Shehbaz türünün daha kuru ve sıcak alanları tercih ettiği tespit edilmiştir.
The status of three names related to the genus Pseudosempervivum is reconsidered. As a result, Noccaea crassiuscula and Pseudosempervivum amanum are reduced to synonymy of P. sempervivum while P. gurulkanii is found conspecific with N. venusta. Problems in delimitation of P. sempervivum and P. aucheri are also briefly considered. The name Cochlearia sempervivum is lectotypified.
Noccaea ali-atahanii, a new Brassicaceae species from southern Anatolia, is described herein. It is mostly similar to N. aghrica, but can be readily distinguished by the presence of apical placentation and orbiculate fruit with wings extending almost evenly from the base to the apex. Its phylogenetic relationships within the genus are provided based on the nuclear-encoded ribosomal internal transcribed spacer region. Carpological and ecological features of N. ali-atahanii and related species are also discussed.
