Reestablishment of Calyptrion (Violaceae)

摘要

Recent revisionary studies on the Neotropical lianescent genera of Violaceae revealed that Calyptrion Ging. is a validly published earlier name for Corynostylis Mart., with species distributed in Amazonia and Central America. The species in the genus are reevaluated and four new combinations are effected, Calyptrion arboreum, C. carthagenense, C. pubescens, and C. volubile. Other nomenclatural issues, including typifications and synonymy, are also discussed.
