406 SMITH: STUDIES IN THE GENUS LUPINUS 
The typical form of this species is mainly confined to the 
Atlantic drainage of the Rocky Mountain region, the exception 
being its occurrence on the “Snake Plains’’ of southern Idaho. 
The New Mexican plants referred here may prove to be a separable 
variety, as the racemes often exceed the foliage and the plants 
suggest the larger phases of L. rubens. Fruiting material, with 
matured seeds, is much desired from New Mexican localities and 
Green River, Utah. The Great Basin form, separated by Heller, 
deserves recognition as a variety, some intermediates occurring.
