As a precursor to a taxonomic monograph of the Neotropical genus Macleania (Ericaceae: Vaccinieae), a comprehensive nomenclatural index of all published names in Macleania is presented. Valid names and invalid designations (including those used in manuscripts and horticulture), along with their current taxonomic and nomenclatural status, are noted. Confusion among Macleania names caused by protologue deficiencies, poor horticultural practices, and redundant publication in trade journals and sales catalogues is detailed and clarified. Brief historical notes, references to published illustrations, and color illustrations of 19 species are included. Ten first-step lectotypes, seven second-step lectotypes, two neotypes, one example of an isonym, and 14 new synonyms are proposed.
