Calceolaria
kal-se-o-la'ri-a (Latin, little shoe), a plant from the Andes of Peru and Chile, belonging to the same family as the toad-flax, mullein, and monkey flower. The flowers are saccate, much like a lady's slipper in outside appearance. The calceolaria makes a fine house plant. The colors are rich and intense, varying from yellow to purple and violet, pure or often dotted with brown spots.
