Hierbas oarbustos sufruticosos, anuales o perennes; tallos procumbentes o trepadores, glabros o densamentepubescentes. Hojas enteras, dentadas o lobadas, mayormente cordatas enla base, pecioladas. Flores solitarias o inflorescencias escorpioide-cimosas oumbeliformes o en capítulos, axilares; sépalos 5, iguales o desiguales, glabroso pubescentes; corola campanulada a infundibuliforme o más o menos rotácea,profundamente lobada, 5-dentada o más o menos entera, azul, lila o blanca;estambres generalmente incluidos, el polen agrecolpado; estilo 1, generalmenteincluido, filiforme, estigmas 2, elipsoidales u oblongos y compresos, ovario2-locular, 4-ovulado, disco pequeño o ausente.Frutos en cápsulas, globosas a ovoides, 2-loculares, 4-8 valvares; semillas1-4, glabras, tuberculadas, aladas o pilosas. Aprox. 80-100 spp. Américatropical y algunas extendiéndose a las zonas templadas, algunas nativas delViejo Mundo y 1 o 2 son introducidas.

  • Morphology

    This genus is very close to Convolvulus and there is no universal distinguishing character. Since however the species are mostly extra-African it would not be wise to sink the genus after study of only a few species.
