Stems are succulent, hairless or with long soft hairs. Stems contain a transparent sticky sap. Leaves have a distinct sheath and blade. Blades are ovate to linear-lance shaped, slightly succulent, and light green. Blade edges often are crinkled.
Venation is parallel.
Inflorescences are clusters of flowers that arise from different points on a stalk, but ascend to the same height. Flowers are subtended by a bract that is green and ascending. Flowers have three pale rose-lavender to white petals and three green sepals. Sepals occur with or without glandular hairs. Stamens have hairy filaments and yellow anthers.
