Family, Pink. Sepals and petals, 5. Stamens, 10. Styles, 3. The pod splits into 3 parts when ripe. Leaves, overlapping, spreading, bristly, awl-shaped. A tufted plant with short and grooved stems. May to August.

Above, the branches are leafless and bear many flowers in cymes. A pretty flower, growing in sand. I have found it growing on the road from Bridgehampton to East Hampton, Long Island, looking brightly out of arid sand where one would think nothing could grow. New York, New Jersey, and southward.
