Figure 13. l-'Ioral parts of Lupinus varie^atns, enlarged 

 flaring at the apex, the groove narrow; wings with a low infla- 

 tion, 4 mm. wide and 4 mm. deep but 6 mm. deep when fully 

 spread out, the upper edges raised into a sharp ridge, on either 

 side of this a broad depression, lower edges closed, completely

The type, in the herbarium of the Nevada Agricultural 

 Experiment Station, is Heller 10^^ i^ collected July 8, 191 2, on 

 the Ruby mountains near Deeth, Elko county, Nevada, at an 

 elevation of 7300 feet. The pods and seeds were obtained about 

 a thousand feet lower, from plants which seemed to be identical 

 but were past flowering. 



The nearest relative of this species is L. calcaratus oi west- 

 ern Nevada. The flowers seem to average larger than those of 

 calcaratus, which are whollv white or purple tinged, are not so
