Barren valley collomia is a small annual species measuring only two to six inches tall and branching when developed. The species is glandular and puberulent throughout, and densely so on the peduncles and calyx teeth. Ciliate on petioles and along lower edges of leaf blades and bracts. There are few leaves on C. renacta, and they are entire with the lower leaves petiolate and spatulate to spatulate-oblanceolate. The leaves are 1.7-2.2 cm long and 4-5 mm wide. The main stems and branches of the plant end in dense leafy-bracteate flower clusters with flowers subtended by bracts that are linear 1.5-2.5 cm long tapering to a slender point. The calyx teeth are narrow, firm aristate-attenuate, and unequal with longer teeth 3-5 mm long when in fruit. The corolla is funnelform and only about 1 cm long with rounded lobes being 2-2.5 mm long and blue with a white throat. The filaments are 0.5 mm long and somewhat unequally inserted slightly below the corolla throat. The style is 5-6 mm long and the stigma is about level to the stamens. The fruits are capsular with three locules each producing a single seed. The seeds are mucilaginous when wet.
