Mojave Indigo Bush

The Mojave indigo bush (Psorothamnus arborescens) is a flowering bush in the legume family. It is found in the Mojave and Colorado Deserts of California and south in the Sonoran Desert in the Mexican state of Sonora. 

All I'm really certain of on this bush is that I only found a few, their flowers were small and hard to photograph, and the flowers were beautiful. 

It has highly branching stems and leaves of green linear to oval leaflets. It has many small flowers with reddish green calyces of sepals and bright purple pealike corollas. 

I am not certain of this identification.
