These are the similar Owens series and the Hensley , Lindy , Lueders , Mereta , Speck , and Tobosa series. Hensley, Lindy, Lueders, and Speck soils are underlain by limestone. Also, Hensley, Lueders, and Speck soils have sola less than 20 inches thick. Mereta soils have a petrocalcic horizon. Tobosa soils have gilgai relief and intersecting slickensides.
Permeability is slow.
Runoff is medium on 1 t 5 percent slopes, high on 5 to 20 percent slopes, and very high on slopes greater than 20 percent. Native grasses are sideoats grama, blue grama, little bluestem, silver bluestem, buffalograss, and Texas wintergrass. The series is extensive. Classification change from Typic Ustochrepts to Vertic Ustochrepts based on laboratory data from Stephens, Throckmorton and Shackelford Counties. COLE data and slickensides indicate the need for the change.
