Pollen Morphology in Erodium (L.) l Hér (Geraniaceae) species in Iran

Erodium is a genus of Geraniaceae with about 75 annual and biennial species which are distributed in almost all continents except Antarctica. In this project pollen morphology of 8 Erodium species of Iran investigated by light and scanning electron microscope. 14 qualitative and quantitative features considered. All studied species showed monad, isopolar, prolate, spheroidal to oblate – spheroidal pollen grains with tricolporate apertures. Exine sculpture was of reticulate – striate to striate and gemmate types. Multivariate statistical analysis revealed the diagnostic value of pollen morphological features in species separation. Based on present study on pollen morphology, grouping result is in concordance with sub-generic classification. Pollen features are capable of Species separation in Erdoium species of Iran.
