Studies on the genusPrunus(Rosaceae) in the Neotropics: taxonomic and nomenclature changes for Colombia

[摘要] As a part of the studies on neotropicalPrunus , initiated with the taxonomic revision for Colombia, three new species are presented with complete descriptions and comments on taxonomy, chorology and conservation ( P. antioquensis, P. littlei , andP. megacarpa ). In addition, five taxa, whose description is based on material from Colombia, have been reduced to synonyms ( P. betancurii, P. carolinae, P. ernestii, P. recurvifloraandP. villegasiana ) and two lectotypes and one neotype are designated. For the newly cicumscribed species herein, diagnostic characters are annotated, synonyms are discussed and their geographical distribution commented upon.
