| Resumen en inglés | Achenes of the thirty seven Valeriana species from the southern Andes were described, illustrated and compared by scanning electron microscopy and stereomicroscopy. It is shown that the detailed analysis of the achenes provides excellent taxonomic characters (e.g. fruit shape, sterile locules development, fruit-coat surface) to distinguish among the southern Argentina and Chile taxa. Results are contrasted with the systematics of this genus. Four informal groups are established, and a key to the South-Andean species of Valeriana is provided, based on achene morphology |
