Note
|
Calceolaria perfoliata is recognized by its peculiar leaves and shape of the anthers. A related species, C. trilobata Hemsl., native of Colombia and Ecuador, has been introduced to Guatemala, but it has not been reported from Panama. It is distinguished from C. perfoliata by deltoid leaf-blades, green sepals and divaricate anther cells. Both species belong to the section Zygophylla Pennell, comprising herbs with perfoliate leaves,
