Comparative pollen morphology of sect. Quinqueloculares (Campanulaceae) in Turkey
Abstract
The pollen morphology of Turkish species belonging to sect. Quinqueloculares (Boiss.) Phitos (Campanulaceae) were investigated with a light microscope (LM) and scanning electron microscope (SEM). All examined species are endemic, except Campanula crispa Lam. According to the results of this study, pollen grains of the examined taxa were triporate and spheroidal. Their sculpture was spinose and baculate (C. crispa Lam.); spinulose and microperforate (C. tomentosa Lam.); microperforate (C. vardariana Bocquet) or more commonly, microechinate (C. iconia Phitos, C. lyrata Lam. subsp. lyrata, C. hagielia Boiss., C. sorgerae Phitos, C. betonicifolia SM., C. karadjana Bocquet, C. telmessi Hub.-Mor. & Phitos, C. davisii Turrill). © 2012 Versita Warsaw and Springer-Verlag Wien.
