The species of Hedysarumcappadocicum is an endemic and distributed in Central Anatolia and EasternAnatolia. The samples of this study were collected from the province of Sivasafter the description the anatomy of the root, scapus, petiole and leafletswere investigated. The anatomical features of the species have been comparedwith the results of previous investigations. The anatomical features of thespecies are presented in this study for the first time in detail. The resultsof the anatomical study described that the species have secondary growth incross-section of root, ribbed structure of cross-section of scapus, isobilateraland amphistomatic leaflets with tannin, triangular shaped petioles andanisocytic stoma type.

WOS: 000387737500025, Tanacetum is one of the large genera, belonging to the Anthemideae tribe of Asteraceae family and has numerous medicinal plants and widely usage in folk medicine. In this study, anatomical features of six endemic species to Turkey viz. Tanacetum albipannosum, T argenteum subsp. argenteum, T cappadocicum, T densum subsp. sivasicum, T haussknechtii and T heterotomum, were investigated for the first time. The specimens were collected from their natural habitats in Sivas province (Turkey). Transverse sections of root, stem, petiole and leaflet were observed under light microscope for various anatomical features. The results showed that, root included periderm in the outer. There were parenchymatous cortex, endodermis and pericycle under the periderm respectively. Primary xylem ridges were triarch in T albipannosum, T densum subsp. sivasicum, T haussknechtii and T heterotomum, pentarch in T cappadocicum and hexarch in T. argenteum subsp. argenteum, and pith was filled with xylem elements. Stem was made up epidermis, parenchymatous cortex, endodermis, vascular bundles and parenchymatous pith from exterior to interior. T heterotomum had a cavity formed by the disintegration of the cells in the center. The amphistomatic leaflets had a single layered epidermis with usually silvery or whitish tomentose indumentum and equifacial mesophyll. Stomata are anomocytic. There were significant difference among examined taxa in respect to contour of petiole, structure of cortex parenchyma and organization of vascular bundles. The anatomical characteristic features of petiole proved to be a useful tool for the taxonomic discrimination of the six studied taxa., Scientific Research Project Fund of Cumhuriyet University [ECZ-028], We thank to Scientific Research Project Fund of Cumhuriyet University, for financial supporting to the present study under the project code ECZ-028.

WOS: 000399440900005, In this study, the morphology, anatomy, pollen morphology, leaf and seed micromorphology and karyology of the Turkish endangered endemic Physoptychis haussknechtii were investigated in detail for the first time. The species was studied in terms of detailed morphology. Basal leaves are narrowly spatulate and cauline leaves are linear to oblanceolate; both leaves are covered with flattened stalked five-armed trichomes. Raceme length was found to be up to 6 cm and 9 cm in the flowering and fruiting stages, respectively. Sepals are linear-oblong, rarely elliptic with obtuse to subacute apex. Petals are spatulate with emarginate apex. Some morphological characteristics such as dimensions of cauline leaves and ovary and length of pistil were measured for the first time. In an anatomical study, root, stem, basal leaf and cauline leaf were examined. The anatomical results showed that the plants have secondary growth in roots, primary growth in stems, amphistomatic and equifacial basal and cauline leaves with anisocytic stomata. Pollen grains are radial symmetrical, isopolar and tricolpate. The ratio of polar axis to equatorial diameter is 1.16, and pollen shape is subprolate. Exine sculpturing is reticulate under light microscope and scanning electron microscope. Seeds are obovate-suborbicular, compressed and pale brown. The chromosome number of P. haussknechtii was defined to be 2n=16. The karyotype formula of P. haussknechtii consists of five metacentric chromosome pairs and three submetacentric chromosome pairs., Scientific Research Project Fund of Cumhuriyet University [ECZ-012], We thank the Scientific Research Project Fund of Cumhuriyet University, for financially supporting this study under the project code ECZ-012.

WOS: 000328438300004, In this study, anatomical and palynological properties of Chaerophyllum astrantiae Boiss. & Bal. and C. aureum L. were determined for the first time. Cross sections of roots, stems, stem leaves and fruits of both species were examined. The leaves are amphistomatic and mesophyll is bifacial The fruit has two vittae on commissural face and four vittae on lateral and dorsal faces in both species. The palynological studies revealed that, C. astrantiae and C. aureum have tricolporate pollen type and perforate exine ornamentation under light microscope. Ratio of polar axis to equatorial axis is 2.15 in C. astrantiae and 2.05 in C. aureum. Thus, pollen shape is perprolate for both of the species.

Bu çalışmada ülkemize endemik Silene lazica ile Silene muradica türleri, makro ve mikro morfolojik, anatomik ve palinolojik özellikleri bakımından incelenmiştir. Sonuçlar literatür bilgileri ve iki tür arasında mukayese edilmiştir. Çalışılan türlerin morfolojik betimleri genişletilmiştir. Örneğin S. lazica’nın yaprak ve tohum boyutları ilk kez bu çalışma ile belirlenmiştir. Anatomik çalışmalarda kök, gövde ve yaprak anatomileri ortaya çıkarılmıştır. Her iki türde de kök ve gövde anatomisinin benzer olduğu ancak S. lazica’nın yapraklarının mezofile göre dorsiventral, S. muradica yapraklarının ise ekvifasiyal olduğu bulunmuştur. İki türün de palinolojik özelliklerinin çok benzer olmasına rağmen ortalama apertür sayısının S. lazica’da 18, S. muradica’da ise 15 olduğu bulunmuştur. Her iki türün de polen ekzin ornamentasyonu miktroekinat–perforate–scabrate olarak bulunmuştur. Mikromorfolojik özelliklerine bakıldığında S. lazica’da sadece viskid salgı tüylerinin, S. muradica’da ise basit örtü tüylerinin gövde, yaprak ve kaliks üzerinde bulunduğu tespit edilmiştir. Meyve mikromorfolojisinde S.e lazica meyvelerinin testa hücre sınırları belirgin ve bu sınırlarla retikulat ornamentasyona benzer diziliş görülürken, S. muradica meyve yüzeylerinin hücre sınırları belli olmayan tuberkulat ornamentasyon gösterdiği bulunmuştur. Tohum mikromorfolojisinde S. lazica mammalian ve spinulat testa hücrelerine sahipken S. muradica’nın benzer uzantılar taşımayan düz yüzeyli hücrelerden oluştuğu tespit edilmiştir. In this study, the endemic Silene lazica species and Silene muradica species were investigated in terms of their macro and micro morphological, anatomical and palynological features. The results were compared between the literature and the two species. The morphological descriptions of the studied species are expanded. For example, leaf and seed sizes of S. lazica were revealed for the first time. Root, stem and leaf anatomies were revealed in anatomical studies. It was found that root and stem anatomy were similar in both species, but the leaves of S. lazica were dorsiventral compared to the mesophyll, and the leaves of S. muradica were equifacial. Although the palynological features of both species are very similar, the average number of apertures was found to be 18 in S. lazica and 15 in S. muradica. Pollen exine ornamentation of both species was found as microechinate–perforate–scabrate. Considering the micromorphological features, it was determined that only viscid glandular hairs in S. lazica and simple cover hairs in S. muradica were found on the stem, leaves and calyx. In fruit micromorphology, testa cell borders of S. lazica fruits are clear and an arrangement similar to reticulate ornamentation is observed with these borders, while S. muradica fruit surfaces show tuberculate ornamentation with unclear cell borders. In seed micromorphology, it was determined that S. lazica had mammalian and spinulate testa cells, while S. muradica consisted of flat–surfaced cells without similar extensions.
