Data on the palynomorphological characterstic of the genus Silene from Albania

The palynomorphological features of four species belonging to the genus Silene (Silene italica, Silene armeria, Silene pusilla and Silene fabarioides) from different regions of Albania, were investigated and studied by light microscope. This study aims to assess and highlight the existence of significant differences in pollen size, distance between two pores, the exine sculpture and pores number found in these species. Pollen grains were usually radially symmetrical, polar, polypantoporate, spheroidal. The pores were circular contours, operculate which due to thickening of intine in this zone, come out like a cupole. The number of pores varied from 20 to 26 in Silene italica, from 16 to 20 pores in Silene fabarioides and Silene armeria, and from 12 to 16 pores in Silene pusilla. The ornamentations of exine varied from microechinate to microperforate (punctate) at Silene italica, Silene fabarioides and Silene pusilla, whereas at Silene armeria the sculpure of exine was reticulate. The biggest pollen grains were found in Silene fabarioides, whereas the smallest ones were found in Silene armeria.

对来自阿尔巴尼亚不同地区的蝇子草属（Silene）4个物种（意大利蝇子草Silene italica、海石竹蝇子草Silene armeria、矮蝇子草Silene pusilla及Fabarioides蝇子草Silene fabarioides）的孢粉形态特征进行了光学显微镜观察研究。本研究旨在评估并阐明这些物种在花粉大小、两孔间距、外壁纹饰及孔数方面存在的显著差异。花粉粒通常呈辐射对称、极性、多泛孔型、球形。孔呈圆形轮廓，具盖；由于该区域内壁增厚，孔盖突出呈穹顶状。意大利蝇子草的孔数为20~26个，Fabarioides蝇子草与海石竹蝇子草为16~20个，矮蝇子草为12~16个。意大利蝇子草、Fabarioides蝇子草及矮蝇子草的外壁纹饰从微刺状到微穿孔状（点状）不等，而海石竹蝇子草的外壁纹饰为网状。Fabarioides蝇子草的花粉粒最大，海石竹蝇子草的花粉粒最小。
