Calceolariaceae

Lady's slipper Calceolaria biflora, photographed by Serge Ouachée.

Belongs within: Lamiales.

The Calceolariaceae was defined by Olmstead et al. (2001) on the basis of molecular analysis as the smallest clade including Calceolaria pinnata, Porodittia triandra and Jovellana violacea. Formerly assigned to the Scrophulariaceae, Calceolaria is one of the few genera included in that family with elaiophores (oil-producing glands ) in the corolla, in the form of a dense patch of glandular trichomes within an infolded lobe of the lower corolla lip (Olmstead et al. 2001). The lower lip of Calceolaria flowers is expanded and modified into a pouch, giving them the vernacular names of lady's purse or slipper flower.
