The taxonomic status of the populations of Armeriafrom the Horconera massif (Córdoba province), previously misidentified or referred to without an explicit identification, is re-examined on the basis of morphological and molecular data. A multivariate analysis indicates that they can be discriminated from morphologically and geographically close taxa using morphometric characters. According to these results, and taking into account the previous evidence that supports extensive reticulation in the genus, a new species, A. trianoi, is formally described. Molecular evidence from our previous works, in particular the nuclear ribosomal ITS sequence data, provides the frame for a discussion on the origin of the new entity. It is suggested that A. trianoimay be the result of introgression of sympatric populations of A. villosasubsp. longiaristatainto a pre-existing taxon, possibly A. filicaulisvar. minorpresently occurring in Sierra Tejeda some 50 km apart. |
