Pollen Morphology of Acinos Miller Species Growing in Turkey

Ayla Kaya and Hatice Kutluk   

Abstract:

The pollen morphology of six taxa of the genus Acinos Miller has been examined under scanning electron microscopy (SEM) and a description of each taxon has been given. Acinos pollen is stephanocolpate (hexacolpate). Two main exine sculpturing types, foveolate-reticulate (only in subspecies of A. troodi) and reticulate have been defined. The dimension for the polar length ranges between 25.8–47.4µm, equatorial width 24.5–34.4µm, colpus length 20.0–40.5µm and colpus width 1.2–2.5µm. The shape is mostly subprolate to prolate, seldomly prolate-spheroidal. The results reveal rather uniform morphological features, however fine details are characteristic to differentiate the pollen taxa. Acinos pollen also share some common morphological features with the other Lamiaceae pollen.

Key words: Acinos, Lamiaceae, morphology, polen, scanning electron microscopy.
