Several erect stems, 6-12 inches tall, grow from the root of this plant; the branches and limbs are covered with stiff, coarse hairs. The leaves are opposite, 3/4-2 3/4 inches long, attached directly to the 4-sided stem. The 2-lipped flowers are 1/2-1 inch long and up to 1 inch across, lavender to purple, with purple stripes in the throat. They grow in the leaf axils on very short stems and are somewhat tucked between the leaves, scattered here and there on the main stem.
Pale lavender to purple, two-lipped bell-shaped flowers occurs in leaf axils in late spring and repeat in late summer with sufficient moisture.
Found on rocky-grassy slopes, silty flats, or above caprock in most western two-thirds of Texas. Well-drained sand, loam, clay, limestone.
