Nomenclatural revision of Celtis (Cannabaceae) described for northern South America, Central America, the Caribbean and the southern United States

In preparation for a taxonomic review and a global phylogeny focusing on the Neotropical lineages of Celtis, the names described to northern South America, the Caribbean, Central America and southern United States were revised. For the northern axis, 87 names were identified, 60 of which have been reviewed in this contribution. Lectotypes are designated for Celtis berlandieri, C. dichotoma, C. jamaicensis, C. litoralis, C. pavonii, C. pubescens, C. riparia, C. rufescens, C. schiedeana, C. swartzii, C. tikalana, C. triflora, C. velutina and Sponia chichilea. Neotypes were assigned to C. berteroana and C. lamarckiana. Thirty-three names did not undergo changes in their typological status and five were excluded. Among the results, we highlight the (unpublished) location of the holotype of Celtis laevigata, as well as the designation of an epitype for this same species.
