      Hierbas saprofíticas, hialinas y carnosas. Sistema radical consistente en (1) un tubérculo globoso con pequeñas raíces (en Mesoamérica), (2) raíces vermiformes, reptantes, ramificadas, y cilíndricas, o (3) un grupo de raíces coraloides. Tallos no ramificados, longitudinalmente 2-sulcados, con 2-4 hojas bracteiformes justamente por debajo de la flor (en Mesoamérica), o teretes con hojas dispersas. Flores solitarias, erectas. Tépalos enteros, de diferentes formas y tamaños, a veces connatos en una mitra (en los paleotrópicos). Tubo floral 6.5-15 mm, casi cilíndrico a urceolado, zigomorfo a actinomorfo. Garganta rodeada por un anillo ornamentado. Estambres 6, péndulos; filamentos cortos, libres; tecas separadas o unidas; lóculos paralelos, longitudinalmente dehiscentes; conectivo más o menos dilatado, con o sin apéndices, a veces formando un tubo de anteras (en los paleotrópicos); lobos interestaminales 6 (en Mesoamérica). Perianto circuncísil y deciduo. Estilo 3-ramificado, cada rama con un estigma, o no ramificado con un estigma capitado. Ovario 1-locular, con 3 placentas parietales (en Mesoamérica) o con 3 columnas placentarias en el centro del ovario. Fruto cupular, carnoso y hialino, coronado por un borde formado por la parte persistente del tubo floral, y por el estilo y estigma(s) persistentes. Semillas angostamente elipsoides a ovoides con costillas longitudinales arregladas en espiral; funículo tan largo como o más largo que la semilla. 9 spp. Estados Unidos, América tropical, Asia tropical, Australia, Nueva Zelanda.
