Hemileuca e mojavensis food plant

[collector]

Last week at Rock Corral - (San Bernardino Co., California) - I found Hemileuca electra mojavensis larva on this plant.
Does any body know what this plant is??
At home, they are doing OK on Eriogonum fasculatum (buckwheat).
Thanks

Hummm maybe that's a Purshia species? Did it have any flowers?

No, there were no flowers.
The plant was about 4 foot tall.
Here is a picture of the plant.
Thanks
