This study reviews the Ficus americana species complex, a group mostly distributed throughout South America. Following the taxonomic analysis of approximately 60 names related to the group, we specify the new Kinuppii series of 9 species, a ramiflorous group which is delimited by the presence of spurs in the branches, a unique characteristic of the new taxon of Neotropical Ficus. Ficus longifolia and F. schippii are included in the new series, but have not previously been cited as part of the F. americana species complex. Ficus clusiifolia, F. fresnoensis, F. guianensis, F. mathewsii, and F. subapiculata are treated as accepted species names and no longer considered varieties of F. americana. Completing the new series are F. albert-smithii and F. sphenophylla. Epitypes were designated for F. clusiifolia and F. longifolia and a neotype for F. herthae. In this study, F. leiophylla is considered a synonym of F. mathewsii as the leaf shape varies considerably within the taxon. Synonyms, analysis of protologues, types, descriptions, taxonomic key, examined materials, and maps complete the analysis. [ABSTRACT FROM AUTHOR]

This work presents the new taxon Ficus series Dugandii characterized by the syconium ostiolar margin with wall curved to the outer side of the syconium, forming a short apical tube, irregularly rounded to triangular. For this study, field trips were carried out and collections of herbarium specimens, types, and protologues were analyzed. The series has 15 species with 50 synonyms proposed here, distributed from Mexico and the Antilles to southeastern Brazil. Names like F. llanensis, F. llewelynii, and F. mitrophora, previously synonymous, are considered correct species names. Lectotypes have been designated for F. acarouaniensis, F. clethrifolia, F. glycicarpa, F. holosericea, F. velutina, Urostigma euomphalum, and U. maximilianum; a neotype for F. frigida; and epitypes for F. holosericea and F. trigonata.
