Resumen:
Valeriana gaimanensis, a new species from Argentinean Patagonia, is described andillustrated. The new species belongs to the subgenus Valeriana and is apparently endemic to theExtra-Andean Patagonia region, where it grows in an extremely arid environment, in contrast tomost Valeriana species distributed in Patagonia. The morphological relationships of V.gaimanensis are discussed in comparison with V. carnosa, which resembles the new speciesmorphologically. Principal component analysis was performed of 28 morphological variables,including specimens of these two species, revealing differences between them. This studyprovides the distribution, habitat, phenology, and etymology of V. gaimanensis, as well as a keyseparating it from the Valeriana species that inhabit the Extra-Andean Patagonia.
