- Аннотация: The aim of our investigation is reconstruction of the dispersal history of Monimiaceae family based on an integrated morphological and molecular analysis. For the reconstruction of the history of dispersal history of Monimiaceae were analyzed 20 species of 18 genera (from 25 total) from all parts of the family range. The objects of the study were 20 species from 18 genera of Monimiaceae. We was selected Gyrocarpus americanus (Hernandiaceae s. l.) as an outgroup. For the molecular analysis the gene 5.8S ribosomal RNA and ribulose-1,5-bisphosphate carboxylase / oxygenase large subunit (rbcL) gene. Using data on the nucleic acid sequences from GenBank, in WinClada program were constructed molecular cladogram for genera of Monimiaceae and Gyrocarpus americanus using bootstrap analyze. Morphological phylogenetic model, which is based on morphological characters of the original data matrix (27 were studied for morphological and anatomical characters), was built to reflect the most parsimony cladogram. The complex cladograms were obtained as a result of the synthesis of molecular and morphological data. Our conclusions are following. Xymalos is basal genus of Monimiaceae, and therefore Xymalos monospora – the basalmost genus of the family. The next clade is occupied by Sri Lanka endemic genus Hortonia. Intrusion of Monimiaceae in South America through Antarctica occurred not later than the end of the Cretaceous period. At present time the southernmost genus in South America is Peumus, it was could be the most resistant to climate change, which allowed him to gain a foothold on the west coast (app. nearly 40 degrees south latitude). Later range of Monimiaceae in South America moved to the north, along with climate change (such genera as Mollinedia, Grazielanthus, Hennecartia, Macropeplus). Based on the Tertiary fossils of Monimiaceae in Oman and Germany, we are conclude that for intrusion to Australia Monimiaceae required to make a long way through the coast of East Africa, South Asia (where, in Sri Lanka, remained ancient oligotypic genus Hortonia) and after to Malesia (Kibara) and Australia (Hedycarya, Palmeria, Austromatthaea, Steganthera, Wilkiea). New Zealand was intrusion by Monimiaceae from Australia (Hedycarya). Madagascar (Decarydendron, Ephippiandra, Tambourissa) and the Mascarene Is (Tambourissa) were intrusion by Monimiaceae from New Caledonia (Kibaropsis, Hedycarya) or Eastern Australia, but it is likely Madagascar could be inhabited by Monimiaceae, which later became extinct. Key words: dispersal history, cladistics analysis, Monimiaceae, molecular data.
