Heterostyly is the occurrence of flowers with different sexual organ arrangements in different plants of the same species. This floral polymorphism occurs in four sections of genus Linum. The present study compares the morphological, palynologycal and genome size (C-value content) characteristics in the long-styled and short-styled plants in three Linum species, that is, Linum austriacum L., Linum album Ky.ex Boiss. and L. glaucum Boiss. & Nöe . 15 qualitative and quantitative morphological characters from both vegetative and reproductive organs of these plants were studied. A higher mean value of the plant height, size of the basal leaves width, flower leaves width, calyx length, sepal length and petal length occurred in the long-styled plants, while the mean value of branch number, basal leaves length, flower leaves length, calyx width, pedicel length and sepal length was higher in the short-styled plant populations. T-test analysis of morphological characters showed significant difference (p
