    Numerical comparative hairs of some Lamiaceae taxa collected from Turkey; [Comparação numérica de pelos de alguns táxons de Lamiaceae coletadas na Turquia]
    (Sociedade Brasileira da Ciencia das Plantas Daninha, 2017) Özdemir A.; Kocabas O.
    In this study, glandular and aglandular hairs were examined and compared numerically in the vegatative and reproductive organs of Salvia viridis, Salvia verticillata subsp. amasiaca, Salvia virgata, Phlomis pungens var. pungen, Phlomis pungens var. hispida, Stachys cretica subsp. anatolica, Stachys cretica subsp. smyrnaea, Teucrium scordium subsp. scordioides. It has been observed that all taxa which are collected Western and Northern Anatolia have glandular hairs and aglandular hairs of various shapes, size and modes of secretion. The hairs variations in eight Lamiaceae taxa were been investigated by means of numerical methods (Analysis of variance and Pearson correlation). It was also found that the results from numerical analysis of the hairs characters can provide additional evidences 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.
