A fjenus confined to AVcstern America, ranging from British Columbia to Mexico and from 

 the Pacific to tiie Rocky Mountains. Tiie half-dozen Mexican species are soniewhat peculiar and 

 form a distinct section. The whole genus is unique, in some of its chai-acters allied to the Tulip 

 of the Old World, in others to tlie Melanthaceous group of genera. The colors of the Howera are 

 in some of the species very variable.
