A diffuse or erect gray-green woody shrublet with lax ascending branches. Stems shortly hairy, 15-50 cm high. Leaves alternate, not fasciculate, reflexed, flat, linear, 0.8-1.5 cm long, 1-2 mm wide, usually as long as or longer than the internodes, the edges thickened and entire or with very minute teeth. Inflorescence branched, the branches spreading or divaricate, rigid, ultimately spinous. Flowers solitary, on rigid pedicels 3-9 mm long, longer than the small leaf-like bracts. Calyx lobes 2-3 mm long, acute, slightly keeled, the edges revolute and toothed at the base. Corolla white, fading to yellowish, sometimes purple outside, 6-8 mm long, the tube about 2 mm long, the lobes slightly hairy on the mid line. Bases of the filaments oblong, subobtuse, often cucullate at the top, densely ciliate. Style coarsely hairy, thickened at the top. Ovary hairy, half-superior, the lower part less than 1 mm long, bulged below the calyx lobes and retuse at the base. Fruit 2 mm diam., the valves slightly shorter than the spreading calyx lobes.
