    An anatomical study of Scilla (Scilloideae) section Chionodoxa and Scilla bifolia in Turkey; [Um estudo anatômico de Chionodoxa incluída na Scilla (Scilloideae) e Scilla bifolia na Turquia]
    (Sociedade Brasileira da Ciencia das Plantas Daninha, 2017) Yildirim H.; Yetisen K.; Özdemir A.; Özdemir C.
    In the present study Scilla luciliae, S. forbesii, S. sardensis, S. siehei, Scilla x allenii and S. bifolia are compared anatomically. Some differences have been found in root, scape, and leaf anatomy of the taxa, and commented. S. luciliae, S. forbesii, S. sardensis and S. siehei have a metaxylem at the center of the root, others have 3-4 number metaxylem. Vascular bundles in two row in S. luciliae and S. forbesii in a single row in S. sardensis, Scilla x allenii and S. bifolia though in three rows in S. siehei. Aerenchyma tissue is present in mesophyll of five taxa leaf except S. sardensis. The anatomical variations in the taxa have been investigated by means of numerical methods (Analysis of variance and Pearson correlation). By the analysis of the investigated taxa from 12 anatomy related characters, it has been also found that the results from numerical analysis of anatomy characters can provide additional evidences, which correspond to the anatomy for the recognition of the taxa. © 2017, Sociedade Brasileira da Ciencia das Plantas Daninha.

    The anatomical studies on two biarum (Araceae) species in Turkey
    (Akademiai Kiado Rt., 2018) Akyol Y.; Durmuskahya C.; Yetisen K.; Kocabas O.; Özdemir C.
    In this study, anatomical properties of Biarum marmarisense (P. C. Boyce) P. C. Boyce and Biarum pyrami (Schott) Engl. var. pyrami were examined. The specimens were collected from Antalya province, South West of Anatolia. Degree of spathe tube margin connection, distribution of pistillodes and staminate-pistillate flower zone interstice length characters are important in Biarum Schott. taxonomy at specific level. The cross-sections of root, stem and leaf parts of the plant were examined and demonstrated by photographs. Although thicknesses of the cell wall of the endodermis and xylem strands are distinguishing features, raphide crystals are same feature in both species. B. marmarisense has observed paracytic stoma types while B. pyrami var. pyrami has anomocytic stoma types. Most of the anatomical properties were similar to the other members of the Araceae family. © 2018 Akadémiai Kiadó, Budapest.

    Morphological and anatomical studies of hippocrepis l. Genus in Turkey; [Estudos morfológicos e anantômicos do gênero hippocrepis l. Na Turquia]
    (Sociedade Brasileira da Ciencia das Plantas Daninha, 2019) Yetisen K.; Özdemir C.
    In this study, the morphological and anatomical features were investigated of three taxon of Hippocrepis L. species which spreading naturally in Turkey. In the morphological part of the study, H. unisiliquosa subsp. unisiliquosa’s stem is erect or decumbent. The species H. ciliata’s Willd. stem is erect. H. multisiliquosa’s L. stem is decumbent. The fruit of H. multisiliquosa is much more convoluted than the other two taxa. There are cilia on the fruit of H. ciliata, but there are not found any cilia the other two taxa. The stem anatomy of all the studied taxa is hexagonal. In the stem cross section of H. ciliata 12-14 vascular bundle are found, H. unisiliquosa subsp. unisiliquosa 12-15 and H. multisiliquosa 12-13. Leaf vascular bundles are arranged regularly, H. unisiliquosa subsp. unisiliquosa have 18-20, H. ciliata have 6-8, H. multisiliquosa have 9-13 vascular bundles. © 2019, Sociedade Brasileira da Ciencia das Plantas Daninha.

    A comparative anatomical study of the genus Puschkinia Adams in Turkey
    (Sciendo, 2020) Yetisen K.; Yildirim H.; Özdemir C.
    In the study, Puschkinia scilloides Adams, P. bilgineri Yildirim, and P. peshmenii Rix et B. Mathew were compared anatomically. Although the stem vascular bundles were arranged in two rows in P. peshmenii, they can observed in three rows in P. scilloides and P. bilgineri. In addition, some differences were found, such as the metaxylem number in the root, number of vascular bundles in the scape, presence of raphide crystals, and number of protruding epidermis cells at the tip of the leaf. These differences have been found to be taxonomically useful for distinguishing these species. Moreover, similarities and differences between Puschkinia Adams and the taxonomically closely related Scilla L. section Chionodoxa Boiss. and Scilla bifolia L. taxa were also discussed. © 2020 Sciendo.
