The genus Pedicularis with 600-800 species is a semiparasitic plant distributed mostly in cold and mountainous regions of the northern hemisphere . In this study, nine species of this genus in the flora of Iran has been studied by electron microscopy . The surface of stigma of P. pycnantha and P. wilhelmsiana are flat. It is hemispherical in P. cabulica , P. caucasica , P. rechingeri, P. sibthorpii, P. condensate, P. strausii and conical only in P. rhinanthoides . In order to determine relationships between species, numerical analysis was carried out using 44 quantitative and qualitative of morphological, anatomical and palynological traits. The diagrams obtained from UPGMA and PCA methods were used to establish the relationship between the studied specie. Based on the results of the analysis, traits such as fruit pericarp thickness , spongy parenchyma thickness of leaf , stem height , stem thickness , total thickness of the stem and midrib length with high variability can be useful for species determination and evaluation of the similarities between them.
