FLO–R–ES, the Flower Research Synectics network is a platform for plant scientists to design, discuss and promote joint collaborative research on diverse flower-related questions.
Founded in 2014, there are currently eight researchers of different countries keeping an active contact and interaction within the network.

Louis Ronse de Craene
Louis Ronse De Craene (Doctorate Leuven, Belgium 1992) is a botanist, working at the Royal Botanic Garden Edinburgh since 2002 as Director of the MSc Course in the Biodiversity and Taxonomy of Plants. His main interests are in floral morphology and development, with the aim of understanding the evolution of flowers. His research concentrates on the circumscription and evolution of specific floral characters, as well as understanding how non-genetic factors affect floral evolution. In 2010 he published an influential book on floral diagrams, as he looks into pragmatic ways of communicating floral diversity and aesthetics. Through collaborative research with several collaborators and other partners of FLO-RE-S, Louis hopes to expand the understanding of morphology as a valuable counterpart of genetics. Current research centers on the significance of changes in merism and the origin and evolution of petals, with special emphasis on Caryophyllales and Rosaceae.
Louis is part of the editorial board of Journal of Plant Research, associate editor of Plant Systematics and Evolution, and subject editor of Flora.

Regine Claßen-Bockhoff is a full university professor at the Institute of Organismic and Molecular Evolution (iomE) at the Johannes Gutenberg-University Mainz, Germany. She is mainly interested in inflorescences and flowers following the philosophy that deep understanding of floral structures demands studies ranging from meristem development to functional phenotypes and evolutionary significance. The main projects of Regine’s lab are i) inflorescence development with a special focus on pseudanthia and floral unit meristems and ii) evolution of the staminal lever mechanism in Salvia flowers (Lamiaceae) including developmental, functional morphological, pollination ecological and phylogenetic work.
Currently, Regine is working on a textbook on organismic botany (Die Pflanze. Evolution und Entwicklung organismischer Vielfalt), which will be published in 2018/2019 by Springer Heidelberg, Germany.
