“…Anatomical characters, like thickness of collenchyma in the lower leaf, thickness of xylem, presence/absence of sclerenchyma, and thickness of inner phloem in stem, may be used along with morphological characters to delimit Cirsium species. Ozcan et al (2015) described the leaf anatomical characters of 26 Cirsium taxa of Turkey. These species could be separated based on the midrib and lamina thickness, the height and width of vascular bundle, and number of stomata, and epidermal cell wall patterns in the abaxial and adaxial surfaces.…”

The genus Cirsium Mill. (Asteraceae) also known as plume thistles with about 250 perennial, biennial or rarely annual spiny species is a phylogenetically unresolved and paraphyletic genus. Cirsium species grow in different ecological conditions and tend to form interspecific hybrids. Some species are morphologically very similar and need to be delineated by additional anatomical and molecular characters. About 28 Cirsium species have been reported in Flora Iranica; they were classified in five sections. Taxonomic investigation of these species was confined to morphology and molecular study of RAPD and ISSR markers. The present study carried out anatomical investigation (leaf and stem characters) of Cirsium species in the country. PCoA analysis of anatomical characters could delimit the studied species and the grouping obtained was almost in agreement with morphological and sectional delineation of the genus. The results obtained are in agreement with several other investigations and all together suggestive of the continued gene flow and introgression between Cirsium species that make taxonomy and phylogenetic relationship of the species difficult.

“…Anatomical and micromorphological characteristics have been used in several taxonomical investigations (Ozcan et al, 2015;Erşen Bak & Merev, 2016). A few of morphological and anatomical studies have been conducted in Rhamnus species in the world.…”

In this study, general morphological characteristics, the leaf and wood anatomical characteristics and, leaf micromorphological features of Rhamnus microcarpa, which is native in Artvin were investigated in detail. Leaves broadly ovate, 3.0-5.5 x 1.9-3.9 cm; stipules 4-7 mm; pinnately 7-10 veined; petiol 6-15 mm. Bud scales dark brown transverse band at the base. Wood was semi-ring porous to ring porous, rays heterocellular, fibers thick-walled especially in latewood. In leaves, dorsiventral mesophyll, hypostomatic type stomata and simple unicellular trichomes observed. Also, epicuticle scales in the lower leaf surface observed. ÖZ Bu çalışmada, Artvin'de doğal olarak yayılış gösteren Rhamnus microcarpa'nın genel morfolojik özellikleri, yaprak ve odun anatomik özellikleri ve yaprak mikromorfolojik özellikleri detaylı olarak incelenmiştir. Yapraklar geniş yumurtamsı, 3.0-5.5 x 1.9-3.9 cm; stipüller 4-7 mm; damar sayısı 7-10; yaprak sapı 6-15 mm'dir. Tomurcuk pullarının tabanında koyu kahverengi enine şeritler bulunur. Odun yarı halkalı veya halkalı traheli, özışınları heteroselüler, özellikle yaz odununda lifler kalın çeperlidir. Yapraklarda dorsiventral mezofil, hipostomatik tip stoma ve basit üniselüler tüyler tespit edildi. Ayrıca, yaprak alt yüzeylerinde epikütikular pullar gözlendi.

“…While the mesophyll layer in the taxa growing at low altitudes is quite loose, it is denser in appearance of the parenchyma cells at high altitudes. This shows that high altitude and inadequate water can trigger further development of the mesophyll parenchyma, and consequently enhance photosynthetic activity (Fahn 1990, Ozcan et al 2015).…”

In this study, anatomical characteristics of leaves and stems of 19 taxa of Thlaspi sensu lato, 9 of which are endemic to Turkey, were investigated in order to determine taxonomic relationships among the studied taxa. The anatomical characteristics of all taxa were determined and assessed using the cluster analysis and the principal component analysis. The transverse sections of the leaves and stems exhibited various diagnostic characters in terms of the pattern of epidermal cell and mesophyll layers, the number and size of vascular bundles, and the thickness of the cortex and endodermis. Important differences were detected in number, size, and index of stomata, and in epidermal cell wall structures in the adaxial and abaxial surfaces. The results showed that the compared anatomical characteristics among taxa are partially compatible with their sectional delimitation in their traditional rank in The Flora of Turkey and the East Aegean Islands. The results also point out that some taxonomic rearrangements may be required. Özet: Bu çalışmada, 9'u Türkiye için endemik olan 19 Thlaspi sensu lato taksonunun yaprak ve gövde anatomik karakterleri, taksonlar arasındaki taksonomik ilişkileri belirleme amacıyla tanımlanmıştır. Tüm taksonların anatomik karakterleri belirlendi ve kümeleme analizi ve temel bileşen analizi kullanılarak değerlendirildi. Yaprakların ve gövdelerin enine kesitleri epidermal hücre ve mezofil tabakalarının yapıları, vasküler demetlerin sayısı ve boyutu, korteks ve endodermisin kalınlığı açısından çeşitli teşhis karakterleri gösterdi. Ayrıca, adaksiyal ve abaksiyal yüzeylerde stomaların sayı, boyut ve indeksinde ve epidermal hücre duvarı yapılarında önemli farklılıklar saptandı. Bu sonuçlar taksonlar arasındaki karşılaştırılmış anatomik özelliklerin Türkiye Florası ve Doğu Ege Adaları'ndaki geleneksel sıralamasındaki seksiyon sınırlamaları ile kısmen uyumlu olduğunu göstermektedir. Elde edilen veriler ayrıca bazı taksonomik yeniden düzenlemelerin gerekli olabileceğine işaret etmektedir.
