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 …
