Celebrating 40 years of legume systematics: the productive career of Gwilym P. Lewis

During his long research career at the Royal Botanic Gardens, Kew, Gwilym P. Lewis has contributed significantly and importantly to the systematics, phylogenetics, biogeography, diversity and comparative biology of neotropical Leguminosae, especially Caesalpinioideae and including mimosoid legumes. His floristic expertise has focused on the drylands and wet tropics of Brazil and the Andes of Ecuador, and he has produced monographic work on the large genus Caesalpinia. His research and publication has been multidisciplinary (including: taxonomic revision, phylogenetic studies, reproductive biology, floral anatomy, phytochemistry and biogeography) and has involved international networks. Gwil Lewis has provided specialist legume identification services which have facilitated legume work in conservation and sustainable use, and guided student training both within Kew and globally. His higher level systematic studies have contributed to an improved legume phylogeny from which the legume research community has developed the new classification of the family. In his long career, dedicated to legumes, Gwil Lewis has seen legume systematics evolve from a taxonomic and floristically focused research community to a phylogenetically-based, hypothesis driven science motivated by questions of global biome distribution to flower evolution and genomics. Dr. Lewis has been a witness to the major changes in our research community over the past 40 years, and particularly since the publication of the first volume of Advances in Legume Systematics in 1981. This symposium is dedicated to Gwilym P. Lewis and to his important contribution to legume systematics.
