Somayyeh Kheiri, Masoud Khayami , Shahrokh Kazempour Osaloo and Ahmad Mahmoodzadeh

Abstract:
Pollen morphology of seven species was investigated by light and Scanning Electron Microscopy (SEM). Pollen grains are monad and elliptic to oblique at the equatorial view, circular-triangle at the polar view, trizonocolporate, isopolar and spheroidal prolate, prolate or perprolate. The pollen is small or medium sized in V. szovitsianum Bioss., V. agrimonfolium (C. Koch) Hub-Mor., V. mucronatum Lam., V. sinuatum L., V. macrocarpum Bioss., V. oreophilum C. Koch var. oreophilum and V. cheiranthifolium Bioss., Exine ornamentation is reticulate but in V. agrimonifolium (C. koch) Hub-Mor., it is microreticulate.
