摘　　要：For ferns and lycophytes, the Neotropics is a hotspot of diversity （3000-4500 species）, and second only to Southeastern Asia in richness and endemism. This paper presents the current state of knowledge on fern and lycophyte systematics in the Neotropics, and emphasizes sampling sufficiency and current taxonomic and phylogenetic knowledge. Plant systematics plays an important role in documenting diversity and geographic distribution patterns that are needed to understand relationships and evolutionary patterns, and a vital role in species conservation. Although in recent decades this field of science has undergone a revolution because of new approaches and techniques, data presented in this work shows that large gaps remain and there is still a long path towards fully understanding fern and lycophyte systematics in Neotropics. Approaches and how to choose areas that should be targeted in order to try to fulfill these knowledge gaps are discussed.For ferns and lycophytes, the Neotropics is a hotspot of diversity （3000-4500 species）, and second only to Southeastern Asia in richness and endemism.
