Galactic distribution of 361 open clusters is considered by one of cluster analysis (taxon analysis) methods. More than a half of the clusters are shown to enter taxons (groups, condensations) with characteristic dimensions of several hundred parsecs. To distinguish physical taxons from random condensations, criteria based on similarity of ages, main sequence blue-end colours, integrated colours and radial velocities of clusters were used. Proximity of these values permits to suppose physical entity and common origin of clusters entering a taxon. A tendency to clumping is more prominent for young clusters but in some cases traces of common origin are preserved during some hundred million years. The number of clusters in a taxon varies from 2 to 14, and the form of a taxon reflects concentration of clusters to the galactic plane. In some cases it is possible to unite some neighbouring taxons into systems of higher order with dimensions up to 2 kpc. A list of 54 taxons including 199 clusters is given.
