Valeriana serratifolia, a new species from the Andean region ofnorthwestern Argentina, is described and illustrated. It can be distinguished from itsclosest morphological taxon, V. macrorhiza, by its entire, spathulate leaves withserrulate margin, and falcate fruits, 2?2.5 mm long, crowned by the reduced annularcalyx shifted toward the ventral face. A phylogenetic analysis based on DNA sequencesof plastid markers trnL?F and trnK intron supported V. macrorhiza as its closest relatedspecies. We also provide a key to differentiate V. serratifolia from the epappose speciesof Valeriana from Argentina., a new species from the Andean region ofnorthwestern Argentina, is described and illustrated.
