The Neotropical tribe Spathicarpeae (Araceae, Aroideae) comprises 14 genera distributed from southern Mexico to Uruguay. Despite its complex taxonomic history, the tribe lacks a comprehensive historical synthesis that could support future phylogenetic and taxonomic studies. Herein we provide a historical review of the classification of Spathicarpeae based on detailed analysis of the pertinent literature, as well as the examination of specimens preserved in many herbaria. A generic identification key and taxonomic notes on various taxa are also presented. This study aims to serve as a framework for forthcoming phylogenetic analyses and taxonomic revisions within the tribe.
