Abstract
In this study the morphological and micromorphologcal characters of Ranunculus Sect. Batrachium species in Iran have been investigated. The characters describe leaf, petal and fruit, in addition to pollen grains in four species of the genus including, R. sphaerospermus Boiss. & Blanche, R. trichophyllum Chaix ex. Vill., R. rionii Lagger and R. peltatus Schrank. Pollen grains were tricolpate and had species-specific shapes. The sculpture of the exine was echinnate in all of the species studied. Seven morphological characters have been studied using statistical methods and SPSS software has been used in order to group the species. These analyses indicated that R. sphaerospermus was a valid species and very similar to R. peltatus. Also, intraspecific diversity in R. trichophyllum was confirmed by statistical methods
