Resumen:
Abstract?Valeriana gaimanensis, a new species from Argentinean Patagonia, is described and illustrated. The new species belongs to thesubgenus Valeriana and is apparently endemic to the Extra-Andean Patagonia region, where it grows in an extremely arid environment, incontrast to most Valeriana species distributed in Patagonia. The morphological relationships of V. gaimanensis are discussed in comparisonwith V. carnosa, which resembles the new species morphologically. Principal component analysis was performed with 28 morphological variables,including specimens of these two species, revealing differences between them. This study provides the distribution, habitat, phenology,and etymology of V. gaimanensis, as well as a key separating it from the other Valeriana species that inhabit Extra-Andean Patagonia.
