The genus Pinguicula L. (Lentibulariaceae):: an overview

The carnivorous genus Pinguicula, which currently consists of about 74 species, is part of the Lentibulariaceae family. All members are active animal and plant organ trappers. The leaves are sticky and constitute flypaper-type traps capable of slow motions. The present review focusses on several aspects of the research activities conducted on this genus. These include the study of its evolution, carnivory, trapping and digestion mechanisms, with a special emphasis on the key role played by the mucilage, its ecology and its pharmacological and culinary utilization. This review also stresses the need for a global taxonomic revision of the genus. Finally, it aims to generate greater interest on these very fascinating plants which are in urgent need of protection.
