“…In these taxonomic revisions, C. iguanaea was considered in the broad sense as a species with a high degree of morphological diversity. The latter two circumscriptions have been widely used in taxonomic and floristic treatments (Baehni 1937, Standley and Steyermark 1946, Nevling 1960, Hunziker and Dottori 1976, Burger 1977, Croat 1978, Romanczuk and del Pero de Martínez 1978, Nee 1984, Burkart 1987, Marchioretto 1988, Dottori and Hunziker 1994, Pérez-Calix et al 1999, Torres and Luca 2005, Martins and Pirani 2009, Novara 2009, Pederneiras et al 2011, Ayala 2015, Machado et al 2019, Majure et al 2020). As a result, the distribution of C. iguanaea was extended from Florida (USA) across the Caribbean to Argentina (Baehni 1936, Romanczuk and del Pero de Martínez 1978, Berg and Dahlberg 2001.…”

Studies on Celtis over the last 50 years have established the role of the pyrene in the delimitation of the species. This structure is of fundamental importance for the understanding of the genus and has recently changed the species delimitation, which was previously very broad and vague. Based on these new findings, we have investigated the Celtis iguanaea species complex. This taxonomic group was previously treated as a single species, but it included several species-level synonyms in the Neotropical region for which no modern taxonomic and nomenclatural revision is yet available. In order to correctly delimit C. iguanaea and the other species accepted here, we conducted a review of all records and herbarium specimens (types or not). The main results include (1) a modified taxonomic concept, (2) a revision of the taxonomy, nomenclature, and synonymy (with new or corrected typifications), and (3) a revision of the distribution ranges. In addition, we re-establishment Momisia tarijensis as a species from southern South America for which a new combination (Celtis tarijensis) and an epitype are proposed. In addition, Sarcomphalus punctatus is newly included in the synonymy of C. iguanaea. Finally, we provide an identification key that distinguishes C. iguanaea from all related species.
