GRANT—A MONOGRAPH OF THE GENUS MIMULUS 123 
puniceus is found, and it is in this overlapping area that most of 
the intermediates have been collected. 
In the middle of the nineteenth century, European gardeners 
secured several hybrid species by crossing M. aurantiacus and 
M. puniceus. These two parents do not have the same natural 
geographical range, M. aurantiacus being confined to the foothills 
in California north of Santa Barbara Co. and M. puniceus ос- 
eurring south of Los Angeles, with its center of distribution near 
San Diego. Therefore, hybrids between them would not be 
looked for except in gardens. 
Economic Usss 
Mimulus has little value from an economic standpoint except 
in furnishing some easily cultivated ornamental plants. On 
account of the crisp leaves and agreeable taste, M. luteus and 
M. glabratus are cooked as greens or in soup or eaten as a salad 
by the natives in many parts of South America. It is locally 
called “placa” or “la polcura.” Hieronymus says that in 
Argentina the leaves of M. parviflorus are considered an excellent 
remedy for liver trouble.
