Abstract: | AbstractA new species from the Andean region of northwestern Argentina is described and illustrated: Sisyrinchium humahuacense. This species can be distinguish from its closest related species by three main characters: the presence of a conspicuous horizontal rhizome, the colour of the flowers and the presence of rudimentary leaves not splitting in fibers. A phylogenetic analysis based on DNA sequences supported the inclusion of S. humahuacense within the genus and as part of the section Segetia. Also, a key to species to identify S. humahuacense is presented herein. |
