Notions on dynamic-catenal phytosociology as a basis of landscape science

Short essential notions of dynamic-catenal phytosociology are defined as the basis of landscape vegetation science. The most important units - vegetation series, geoseries, permaseries and geopermaseries (sigmetum, geosigmetum, permasigmetum and permageosigmetum) - are discussed and synthesized in several figures.
