First time I've seen these, Desert Indianwheat, with such green leaves.

Recorded Range: Desert Indianwheat is found only in the southwester United States and Mexico. In the U.S. it is found in AZ, CA, NV, TX and UT. In Arizona it is abundant in most of the state but with few records in Apache, Greenlee and Santa Cruz counties. It is also native to Baja California, Mexico and the Mediterranean.

Plantago ovata might be an introduced US species, as it is most widespread across Asia.
