Macro-and micromorphological features of fruit and seeds belonging to 12 taxa genera of Matthiola W.T.Aiton were studied via stereomicroscope and scanning electron microscope. In macromorphological studies, the following variables were investigated: the shape, size, and color of fruit and seeds; the length of fruiting pedicel; the structure of the median vein; stigma (horns); and trichome properties and density in fruit. In micromorphological studies, the presence or absence of seed wings, seed coat pattern in disc and wing, and epidermal cell shape in disc and wing were determined. According to our findings, all characters of fruit and seeds are extremely variable and can be used as criteria to distinguish species of the genus.

IntroductionBrassicaceae, the vascular plant family, consists of 321 genera and 3660 species (Al-Shehbaz, 2012). The cosmopolitan Brassicaceae family is abundant in the northern hemisphere. Currently, there are 49 recognized Brassicaceae tribes into which more than 90% of the genera have been allocated based on molecular analysis (Warwick et al., 2010).A recently published study titled "The Families and Genera of the Vascular Plants" reported that the genus Matthiola is represented by 50 species worldwide, but most of them are found in Eurasia and Africa (Appel and Al-Shehbaz, 2003).Matthiola has 10 taxa in the flora of Europe (Ball, 1964), 6 in the flora of Palestine (Zohary, 1966), 17 in the flora of Iran (Rechinger, 1968), and 15 in the flora of the former USSR (Komarov, 1977). Matthiola has 10 species in Turkey (Mutlu, 2012). The taxa Matthiola ovatifolia (Boiss.) Boiss. and Matthiola trojana have recently been added to the flora of Turkey (Davis, 1988;Dirmenci et al., 2006).Molecular methods have an important role in the identification of phylogenetic relationships within Brassicaceae. Molecular phylogenetic studies have contributed significantly to the generic delimitation on this family (

The Brassicaceae (Cruciferae) is one of the most important groups and it has 338 genera and 3709 species around the worldwide. Plant samples of the Brassicaceae family were collected and photographed during the vegetation period of 2017. The plant samples and the photos were taken from their natural habitat between 23 April and 11 August 2017. The locations were determined based on differences in geographical features with variable ecological conditions. 38 genera and 80 species and subspecies were identified from different locations of the study area. Heldreichia bupleurifolia Boiss. subsp. rotundifolia, Aethionema caespitosum, Thlaspi lilacinum, Tchihatchewia isatidea, Bornmuellera cappadocica, Aurinia rupestris subsp. cyclocarpa, Alyssum stylare, Alyssum pseudomouradicum, Alyssum peltarioides Boiss. subsp. peltarioides are endemic taxa for Bayburt.

Amasya'da yetişen Calepina irregularis türünde ağır metal birikimi ve biyomonitör olarak kullanılabilirliğinin araştırılması Abstract: In this study, heavy metal accumulation (Ni, Fe, Co, Mn) in Calepina irregularis (Asso) Thell. (Brassicaceae), growing naturally in Amasya province, and the usability of it as abiomonitor was investigated. The amount of heavy metals in the root, stem and leaves of plants which were collected from the city center, near the highway, suburban and non-traffic (control) localities, were determined by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and the obtained data were evaluated. The Ni, Fe, Co and Mn values in compete plants, growing in traffic areas, were found between the ranges 14.32-35.66 mgkg -1 , 827.61-2716.72 mgkg -1 , 12.52-16.51 mgkg -1 and 175.93-826.75 mgkg -1 respectively. The amount of element accumulation in the plant was listed as Fe>Mn>Ni>Co. Ni and Mn were found to be higher in plants growing near the highway while Fe and Co were higher in plants collected from city centre. Heavy metal accumulation was higher in leaves and roots of the plants growing around the highways while it was higher in stems of the plants growing in suburban areas. According to the correlation with plant and soil samples taken from the localities, the relationship between soil and plant, Fe and Mn contents was found significant at P<0.01 level. This shows that the plant receives Ni and Co elements due to air pollution, and that Fe and Mn are mostly taken from the soil through its roots. According to the results of the study, C.irregularis can be used as a biomonitor since it can monitor the short term changes in environmental pollution in urban areas due to its wide distribution area and it has several individuals in its habitat and its conformity with standard analysis methods.Özet: Bu çalışmada, Amasya ilinde doğal olarak yetişen Calepina irregularis (Asso) Thell. (Brassicaceae) türünde ağır metal birikimi (Ni, Fe, Co, Mn) ve biyomonitör olarak kullanılabilirliği araştırılmıştır. Şehiriçi, otoyol kenarı, kenar semt ve trafiğin olmadığı alanlardan toplanan bitki örneklerinin; kök, gövde ve yapraklarında ağır metal miktarları İndüktif Eşleşmiş Plazma-Optik Emisyon Spektrometresi (ICP-OES) ile belirlenmiş ve elde edilen veriler değerlendirilmiştir. Trafik bulunan alanlarda yetişen bitkilerin toplam kütlesindeki Ni, Fe, Co ve Mn değerleri sırasıyla 14.32-35.66 mgkg -1 , 827.61-2716.72 mgkg -1 , 12.52-16.51 mgkg -1 and 175.93-826.75 mgkg -1 aralığında bulunmuştur. Bitkide element biriktirme miktarı Fe>Mn>Ni>Co şeklinde sıralanmıştır. Ni ve Mn elementi yol kenarında yetişen bireylerde, Fe ve Co ise şehir içinde toplanan örneklerde yüksek değerde tespit edildi. Yol kenarında yetişen bitki örneklerinde yaprak ve kökte ağır metal birikimi daha fazla olurken, kenar semtte yetişen bitkilerde ise gövde de birikim daha fazla bulunmuştur. Lokalitelerden alınan bitki ve toprak örnekleri ile yapılan korelasyona göre toprak ve bitki Fe ve Mn içerikleri arasındaki ilişki P<0.01 düzeyi...
