A taxonomic synopsis of the genus Zornia J. F. Gmel. (Leguminosae: Papilionoideae) for the Neotropics

This study updates the taxonomic and distributional knowledge of Zornia in the Neotropics and includes an identification key, field photographs, maps and conservation assessments based on IUCN Red List criteria. The research involved reviewing literature and analyzing specimens from 50 herbarium collections, documenting 50 species in the Neotropics. Conservation assessments indicate significant concerns for many Zornia species, with only three classified as Least Concern.

Additionally, the study provides second-step lectotypifications for two species and re-establishes two other names at species rank. This study contributes to a refined understanding of Zornia taxonomy and emphasizes the need for targeted conservation efforts in the Neotropics.
