Discussion

Variety olanchense is known only from Olancha Peak, Tulare County. It is worthy of cultivation as a rock-garden plant. In Baja California, var. oresbium Reveal is similar; that taxon is restricted to the Sierra Juárez and Sierra San Pedro Martír, but already has made its appearance as a cultivated rock-garden plant.
