Název v původním jazyce

A taxonomic study of selected European taxa of the Tortula muralis (Pottiaceae, Musci) complex: variation in morphology and ploidy level

Popis výsledku v původním jazyce

Four European taxa of the Tortula muralis complex (T. lingulata, T. muralis var. aestiva, T. muralis var. muralis, T. obtusifolia) were evaluated using multivariate analysis of morphological characters, a cultivation experiment and cytological screening(flow cytometry, chromosome counts). This study revealed that only T. lingulata is morphologically well defined within the complex and several new sporophytic characters that can be used to distinguish this taxon from the superficially most similar T. obtusifolia. The traditionally recognized taxa T. muralis var. muralis, T. muralis var. aestiva and T. obtusifolia showed continuous variation, with frequent intermediate plants. However, the main character of the gametophyte used for determination (costaexcurrency) proved to be stable in cultivation, indicating that this character is under genetic control. Additionally, rather complex and only partly species-specific patterns of ploidy variation were found within the complex. Tortula lin
