Calceolaria

Calceolaria (Latin, calceolarius, “shoemaker”), genus of plants native to South America. Most grow in the Andes at altitudes of more than 2,736 m (9,000 ft). The calyx (outer floral whorl) has four parts, and the corolla (inner floral whorl) has two lips, of which the lower in some species resembles a slipper, hence its common name slipperwort. The flowers are most frequently yellow; purple ones are also fairly common. Calceolarias were introduced into floriculture about 1830 and have produced many hybrids and varieties. The plant is a perennial but is often treated as a semi-hardy or greenhouse plant in cultivation. See Figwort.

Scientific classification: The genus Calceolaria belongs to the family Scrophulariaceae.
