Abstract

Ipomoea littoralis (Convolvulaceae), a member of Ipomoea section Batatas, is the only species of the section native and still endemic to the Old World. In spite of confusion in the literature, the correct name for the species is I. littoralis. Plants with which I. littoralis has been confused are endemic to Australia and are properly called I. gracilis. These two names apply to species belonging to different sections of Ipomoea. Ipomoea littoralis probably shares a common ancestor with I. ramosissima of the neotropics. Data from a variety of sources, including common association with people and the many vernacular names for the plants, indicate that they are not only wild but are also encouraged and even cultivated.

Résumé

Ipomoea littoralis, una especie del viejo mundo que pertenece a la sección Batatas de Ipomoea, es la única de la sección que es nativa y aún endémica a ese hemisferio. A pesar de la confusión en la literatura, el nombre correcto para la especie es I. littoralis. Plantas con las cuales I. littoralis ha sido confundida son endémicas a Australia y deben ser llamadas I. gracilis. Estos dos nombres se aplican a especies pertenecientes a dos secciones distintas de Ipomoea. Probablamente I. littoralis tiene un ancestro en común con I. ramosissima de los neotrôpicos. Datos de una variedad defuentes, incluyendo un asotiación común con el hombre y muchos nombres vulgares para las especies, indican que no solamente son silvestres pero también el hombre las fomenta e incluso las cultiva.
