Leaf and stem anatomical structures of three genera (۸ taxa) of subfamily Alsinoideae (Caryophyllaceae) is provided for the first time from Iran. There are great morphological similarities among some species so there are difficulties in species identification. Leaf and stem anatomical studies of ۴۲ populations from different habitats are used to distinguish different taxa. A total of ۴۲ qualitative and quantitative anatomical characters are studied. Inter and intra-specific relationships among species are evaluated and diagnostic value of the anatomical features are considered. Statistical analysis confirms the diagnostic value of leaf and stem anatomical features in studied taxa.
