Linaria Miller With more than 150 taxa is the largest genus of the tribe Antirrhineae. This study was carried out on the species of Linaria that growing in Iran. Some of these species are native to Iran. Internal transcribed spacer (ITS) sequences were obtained for 37 samples representing 6 sections of Linaria recognized by recent taxonomic treatments from Iran. In addition, we used 82 previously ITS sequences from GenBank to test the monophyly of Linaria. Phylogenetic analysis were conducted using Bayesian inference and maximum likelihood. The results indicate that Linaria species from Iran constituted a monophyletic group within the Antirrhineae. data analysis indicates that the classification of species according winged or wingless seeds so not true, so seed morphology especially seed wing that have been considered as useful for the taxonomy of Linaria species, appears to be a homoplasious character in Linaria. Bayesian inference and maximum parsimony analyses confirmed Two sections of Linaria including Macrocentrum and Versicolores from Iran are monophyletic, while monophyly of sections Linaria, Diffusae, Supinae and Speciosae are unsupported by this results. To determine the evolution of Linaria use of morphological characteristics coupled with molecular data will be most effective.
