Guillenia rostrata Greene, Leaflets, 1: 228, 1906. 



No. 8183, collected May 5, near Laws, Inyo county, in 

 sandy and gravelly places about shrubs, growing in company 

 with G. cooperi, which it resembles considerably, but is distin- 

 guished by its more branching habit, glaucous appearance, and 

 leaves tapering at the base instead of sessile and sagittate. The 

 type was collected "in alkaline soil at the Steamboat Springs 

 near Washoe City," Nevada. Professor Greene informs me that 

 the name '■''rostrata*'' was inadvertently printed as cited above in- 

 stead of longirostris
