In this study, pollen morphology of some endemic species belonging to Scrophulariaceae family and their distribution limited to Erzincan was studied by using Scanning Electron Microscope (SEM). Pollen sizes, pollen types, pollen patterns, polen ornaments and apertures tructures of Scrophularia erzincanica, Scrophularia fatmae, Verbascum leiocarpum, Verbascum ozturkii were investigated. In both Scrophularia species pollen size is medium and polen types tricolpat. Although pollen form of two species is close to each other, Scrophularia erzincanica was found to be subprolate and in Scrophularia fatmae it was perprolate. Ornamentations were determined as verrucat and reticulat respectively. In the study of Verbascum species; In the two types studied, it was found that the pollen size was medium-sized, the pollen shape was spherodial in Verbascum leiocarpum, the subprolate was Verbascum ozturkii, the polen types were tricolpate and their ornamentations were reticulate. When the findings of the studied species are evaluated, it is thought that polen morphologies in Scrophularia speciesare not enough to be used in the differentiation of taxa, and Verbascum species shows differences in polen type and it can be used in distinguishing taxa in this context.

This study includes on the taxonomic evaluation of morphological and anatomical features of seeds belonging to Iris taxa, which are I. suaveolens, I. sintenisii, I. foetidissima and I. germanica scattered in Turkey. Morphological features like dimension, shape, colour, and surface ornamentation types of seeds have studied by light and scanning electron microscopes. The structure and thicknesses of testa and parenchyma layers in seeds have examined anatomically. The obtained results show that the color, shape, testa structure and thickness of the seeds of the examined taxa are different in some respects. Furthermore, the surface ornamentations are somewhat diverse for the studied taxa at the interspecific level. As a result, it has been determined that the examined morphological and anatomical characteristics of the seeds show variations with some exceptions, and this situation has a taxonomic importance.
