Operculina
Bejucos volubles, con látex lechoso. Tallos, pecíolos, pedúnculos y pedicelos usualmente alados. Hojas alternas, pecioladas; láminas simples, enteras o lobadas; estípulas ausentes. Flores bisexuales, actinomorfas, solitarias o en cimas dicasiales simples, axilares; pedúnculos más largos que los pecíolos. Cáliz campanulado, con 5 sépalos iguales o desiguales, usualmente no verdes, acrescentes y lignecentes en el frutos, irregularmente dentados en los márgenes; corola campanulada o anchamente infundibuliforme, el limbo entero o pentagonal; estambres 5, insertos, las anteras retorcidas después de abrir; ovario súpero, 2-locular, el estilo solitario, con dos estigma subglobosos. Frutos capsulares, ovoides a globosos, circuncísiles, con el exocarpo separándose a manera de un opérculo, las restantes capas de la pared del fruto abriendo irregularmente, o 4-valvadas; semillas 4 por fruto, glabras o aterciopeladas. Género pantropical con alrededor de 12 especies, con la mayoría de las especies nativas de Centroamérica y el norte de Sudamérica.
