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. The two anther halves are connected by a broad trape zoidal piece of tissue. Pistils have ovoid ovaries covered by short, stiff, glandular hairs.
