Abstract

Studies of morphology, anatomy, ecology, phenology, cytology, palynology, phytogeography, and an analysis of related genera form the basis of a major tribal re-arrangement in the Convolvulaceae, and a systematic study of the American members of the tribe Erycibeae. Detailed results of the palynological and anatomical studies will be reported later. Field studies in Peru, Venezuela, Guyana, and Brazil, along with greenhouse grown plants from Brazil and Panama have aided in the understanding of some of the biological relationships of the taxa. Specimens, including types, from 23 major North and South American, and European herbaria have been utilized in this study, which has led to the recognition of eleven new taxa: one new subgenus, two new sections, three new subsections, five new species, two new varieties, and two new combinations. Keys, descriptions, typification, synonymy, and specimen citation are included for each taxon.
