Abstract
While Preslia, the journal of the Czech Botanical Society, publishes any important contribution on plant systematics, phytogeography, ecology and vegetation science from central Europe, some topics have been raising systematic attention of botanists working in this region and became a kind of the journal's flagship; these include namely datasets of national significance, with focus on flora and vegetation of the Czech Republic. In terms of editorial policy, Preslia puts emphasis on insightful elaboration of the topics addressed, such as thorough taxonomic and phytogeographic treatments, supported by the knowledge of mechanisms generating variation patterns and their evolutionary implications, or, in ecology and vegetation science, robust analyses of solid data sets allowing for generalizations over time and space.
