Graceful plants, which are usually found growing in small patches, as the rootstocks send up flowering stalks at intervals of a few inches. Stems two inches to two feet high, slender, weak, four-angled, and roughened on the angles, simple below the flower-cluster. Leaves opposite, narrowly lance-shaped, broadest just above the base, the lower ones smaller than those near the top. Flowers in loose, terminal, many-branching cymes, on very slender, spreading pedicels; sepals narrow and pointed, slightly shorter than the five white petals, which are so deeply cleft as to look like ten, the blossoms being nearly a half-inch broad; stamens usually ten, sometimes fewer; styles usually three, occasionally four or five. Capsules oblong-ovoid, exceeding the
