Leaf: opposite, near inflorescence alternate; petioled; blade flat, lanceolate or cordate, generally glabrous, often glaucous. Inflorescence: flowers 1 [or whorled], axillary [terminal], peduncled [not]. Flower: +- 1 cm diam; hypanthium obconic; sepals 4, 2 larger, leaf-like, 2 smaller, awl-shaped; petals fused at base; stamens many, outer sterile, petal-like, inner incurved, white or yellow; ovary inferior, chambers 4, placentas axile, style 0, stigmas 4.
