    Statistical comparison on numerical anatomical values of crocus L. Taxa
    (Pakistan Botanical Society, 2018) Özdemir A.; Akyol Y.
    This study aims to statistically compare the nümerical values of root and scape anatomy of 13 Crocus taxa. Anatomical variations in 13 Crocus L. taxa have been investigated by means of numerical methods (Analysis of variance and Pearson correlation). By the analysis of the investigated taxa from ten anatomy related characters, it has been determined that endodermis width, pericycle length and trache cell diameter are the best character pairs which represent the variations in them. It has been also found that the results from numerical analysis of the anatomy characters can provide additional anatomical evidences for recognition of the taxa. © 2018, Pakistan Botanical Society.

    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.
