Labellum Micromorphology Of Some Orchid Genera (Orchidaceae) Distributed In The Black Sea Region In Turkey, Şenay Süngü Şeker, Mustafa Kemal Akbulut, Gülcan Şenel
Turkish Journal of Botany
A detailed micromorphological analysis of the labellum was carried out using both light and scanning electron microscopy on 14 genera (Anacamptis, Cephalanthera, Coeloglossum, Dactylorhiza, Gymnadenia, Himantoglossum, Limodorum, Neottia, Orchis, Ophrys, Platanthera, Serapias, Spiranthes, and Steveniella) of Orchidaceae in Turkey. In the samples, various epidermal features were identified in the spur that developmentally are invaginations of the labellum and the adaxial surface of the labellum. Typical secretory cells and inclusions such as starch or calcium oxalate crystals of different sizes and shapes were found within the structure of individuals. In many genera, characteristically shaped secretory trichomes and papillae were concentrated at …

In this study, the achene surfaces of 31 taxa belonging to the genus Centaurea L. Were examined in detail by means of electron microscopy. The main aim of this study was to characterize the microsculpture of the achene surface of the Turkish species of Centaurea sect. Acrolophus (Cass.) DC. (Asteraceae). Detailed descriptions of the achene surface were given for each taxon and a fruitful dendrogram was established by numerical analyses derived from the determined micromorphological features. The relationships among the taxa studied were briefly assessed using this generated dendrogram. The results indicated that the examined taxa had very high variations …
