This volume is dedicated to Professor Wolfgang Frey to commemorate his formal retirement from The Freie Universität Berlin. It reflects his wide range of research interest, spanning from bryophytes (systematics, morphology, phytosociology, phytogeography, ecology, dispersal and distribution) to vascular plant geobotany. The volume includes contributions from the following fields: morphology-based and molecular-based taxonomy, phytosociology, life-strategy and dispersal of bryophytes, clonal reproduction and population structure of phanerophytes, ecology, physiology and vegetation. Most of the papers have been written by colleagues, former scholars and friends to honour his scientific and academic career.
