The present thesis has three objectives: 1. Characterize the foliar architecture of Iryanthera species; 2. Develop a key for the identification of Iryanthera species from leaf characteristics only; and 3. Determine the distribution of Iryanthera species. The study area corresponded to three biogeographic subregions: Amazon, Caribbean and Chaco. For the characterization of the foliar architecture, 31 leaf characteristics of 887 specimens were taken into account; the key was elaborated with the main diagnostic characteristics, and was of the dichotomous type; the distribution of the species was made from the geographical coordinates of 5050 specimens. New measured characteristics of the 23 species of Iryanthera are presented, a dichotomic key has been developed with foliar characteristics (although some species cannot be differentiated with these characteristics). The most important characteristics for the differentiation are: length of the pecio, roughness of the foliar surface, shape of the lamina, number of secondary veins, length of the lamina, collecting vein, among others. Iryanthera species are distributed from Guanacaste in Costa Rica to Cochabamba in Bolivia including parts of the territories of Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guyana, Panama, Peru, Suriname and Venezuela. It also presents a modification of a taxonomic state and two possible new species.
