Tripolium genus is represented by the only species Tripolium pannonicum (Jacq.) Dobrocz. The individuals of this species feature variable morphological characters due to wide distribution area of the species covering vast territory from the Atlantic coast of Europe through the Pacific Ocean. As a typical halophyte, it grows in azonal communities of several latitude zones. The study was based on the analysis of morphological characters which used to be diagnostic in distinguishing between the closely related taxa: T. pannonicum (Jacq.) Dobrocz. subsp. tripolium (L.) Greuter. (T. vulgare s. str.) and T. pannonicum (Jacq.) Dobrocz. subsp. pannonicum. The significance of morphological diagnostic characters in protologs and subsequent botanical literature is discussed. Such morphological characters as presence/absence of heterocarpy and stem branching pattern are stated to be independent of geographical distribution of populations. They rather represent an adaptive character of propagation in annual plants of Tripolium pannonicum (Jacq.) Dobrocz. under variable environmental conditions of under flooding zone.
