    Comparative Micromorphological and Anatomical Investigations on the Subsection Distantes R. Bhattacharjee (Stachys L./Lamiaceae)

    Açar, Mikail; Satil, Fatih

    In this study; comparative anatomical and micromorphological studies were performed on the subsection Distantes of the Stachys L. genus (Lamiaceae). Also, it was determined distinctive anatomical characters for the taxa of subsection in the study. In anatomical studies, free-hand cross-sections and the paraffin embedding method was applied with the microtome. Micromorphological studies were performed in LM (Light Microscope) and SEM (Scanning Electron Microscope). In anatomical studies, besides of similarities in stem and leaf structures there were also some differences in taxa. In micromorphological studies, the trichome and nutlet characteristics were found to be useful characters on taxa and at species and subspecies level. As a result of the study, the presence of sclerenchyma like a bundle in the stem structure and the presence and types of glandular trichomes and ornamentation on the surface of nutlet, the presence of the wing and ventral structure in the nutlet were important characters that can be used to distinguish taxa. According to the numerical findings, trichome and nutlet micromorphological characters were more important than anatomical characters.

    MICROMORPHOLOGICAL AND ANATOMICAL INVESTIGATION ON SIX SPECIES OF ONOSMA L. (BORAGINACEAE) FROM TURKEY

    Selvi, Selami; Polat, Ridvan; Babacan, Ebru Yuce; Rahman, M. Oliur; Çakilcioglu, Ugur

    Micromorphology and anatomy of six Onosma L. species, viz. O. argentata Hub.Mor., O. neglecta Riedl, O. proballanthera Rech. f, O. rechingeri Riedl, O. sericea Willd. and O. stenoloba Hausskn. ex Riedl from Turky were investigated. Stem anatomy revealed that cuticle layer ranged from 0.6 mu m in O. argentata to 1.7 mu m in O. proballanthera. Parenchymatous cells of O. neglecta and O. stenoloba possessed more intense starch than the other species studied. In leaf anatomy, the longest palisade parenchyma was found in O. neglecta, while the smallest was noted in O. argentata. Mesophyll structure of O. argentata, O. sericea and O. rechingeri was equifacial (isobilateral), while O. neglecta, O. proballanthera and O. stenoloba presented bifacial (dorsiventral) structure. Rugose nutlet ornamentation was observed in O. argentata, O. neglecta and O. sericea, whereas reticulate type was found in O. proballanthera, O. rechingeri and O. stenoloba. Onosma stenoloba could easily be distinguished from other species by its aesterotrichous indumentum, and in contrary, other species possessed haplotrichous type of indumentum. Micromorphological features of nutlet surface, anatomical features of epidermal surface (trichomes and stomata), and lamina mesophyll structure (dorsiventral and isobilateral) could be useful in solving taxonomic problem of the genus.

    Morphological, anatomical and cytological investigations on three taxa of Centaurea L. (Asteraceae) from Turkey

    Tasar, Neslihan; Doğan, Gülden; Kiran, Yaşar; Oliur Rahman, M.; Çakilcioğlu, Uğur

    Morphological, anatomical and cytological features of three Turkish taxa of Centaurea L., viz. C. polypodiifolia Boiss. var. polypodiifolia, C. urvillei DC. subsp. urvillei and C. urvillei subsp. armata Wagenitz were investigated. Stem anatomy revealed the presence of a thick cuticle layer outside the stem, and epidermis with dense hairs was observed in the lower part. Investigation on leaf anatomy showed that different types of hairs on the outside of the leaf were very intense. Palisade parenchyma was observed below the upper and lower epidermis. In Centaurea polypodiifolia var. polypodiifolia, chromosome number was found to be 2n=16, while in C. urvillei subsp. urvillei and C. urvillei subsp. armata 2n=20. Total karyotype length of C. polypodiifolia var. polypodiifolia, C. urvillei subsp. urvillei and C. urvillei subsp. armata was 22.9 μm, 37.84 μm and 40.01 μm, respectively. Among the investigated taxa the karyotype asymmetry index was found lowest in C. urvillei subsp. armata. Satellite was detected in C. urvillei subsp. urvillei and subsp. armata, while it was absent in C. polypodiifolia Boiss. var. polypodiifolia.

    COMPARATIVE VEGETATIVE ANATOMY AND FRUIT MICROMORPHOLOGY OF THE GENUS KUNDMANNIA SCOP. AND THEIR TAXONOMICAL SIGNIFICANCE

    Paksoy, Mehmet Yavuz; Polat, Ridvan; Çakilcioglu, Ugur

    Kundmannia Scop. is a genus of the Apiaceae (Umbelliferae) family which consists of 463 genera and ca. 3500 species. Kundmannia belongs to the Oenantheae tribe and are well represented in Spain, France, Italy, Turkey, Syria and North Africa where they grow on calcareous or siliceous soils. In this study; fruit micromorphology and the vegetative anatomy of the Kundmannia species growing in Turkey were compratively examined for the first time. The anatomical sections were taken from the stem, ray, leaf and and petiole of the plants for taxonomic deduction. Various tissues of taxa were given comparative micro anatomical measurements according to the anatomical studies, lignified or non-lignified medullary rays in stems, stomata types (diacytic and anomocytic), stomata index ratio (0.58 - 0.7), fruit shape and fruit epidermal surface are considered as important anatomical characters. In the fruit micromorphology, the cells on the mericarp surface have seen as striate and rugulate while the surface between the two ribs in the species have observed rugulate or striate. Fruit micromorphology and vegetative anatomy of the genus Kundmannia has not been studied before. However, the anatomical structure of the genus has been elucidated in this study, for the first time.

    The anatomical and micromorphological properties of three endemic and medicinal Salvia species (Lamiaceae) in Erzincan (Turkey)

    Polat, R.; Cakilcioglu, U.; Selvi, S.; Türkmen, Z.; Kandemir, A.

    In this study, we comparatively investigated three endemic Salvia species spreading in Erzincan (Turkey) in terms of anatomy and micromorphology. For anatomical investigation, cross sections taken from stems and leaves of the species were examined under light microscope. For micromorphological investigation, epidermal surface and nutlet structure were examined using scanning electron microscopy. The S. euphratica and S. divaricata species were examined anatomically and micromorphologically for the first time, and S. hypargea was examined micromorphologically for the first time. In anatomical examinations, it was seen that stem and leaf structures of the species were similar. In micromorphological analyses, it has been seen that hairiness of the nutlet surface and nutlet ornamentations (verrucate and rugose type) created a difference between the species.

    COMPARATIVE ANATOMY OF STEM AND LEAF OF RICOTIA L. GROWING IN TURKEY

    Selvi, Selami; Paksoy, Mehmet Yavuz

    The present paper deals with a comparative anatomy of stem and leaf of Ricotia species growing in Turkey. In addition, stomatal index and rate of these species were calculated. A diagnostic key based on combined stem, leaf and leaf epidermal characteristics were presented. The presence or absence of trichome, cortex parenchyma layer, sclerenchyma, mesophyll structure and epidermal surface were found to be important characters for the identification of Ricotia species.
