Fecha de publicación: | 2001 | Editor: | John Wiley & Sons | Citación: | Botanical Journal of the Linnean Society 135 : 71-84 (2001) | Resumen: | The taxonomic status of the populations of Armeria from the Horconera massif (Co´rdoba 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. trianoi may be the result of introgression of sympatric populations of A. villosa subsp. longiaristata into a pre-existing taxon, possibly A. filicaulis var. minor presently occurring in Sierra Tejeda some 50 km apart. | Descripción: | The definitive version is available at http://onlinelibrary.wiley.com/ | Versión del editor: | http://onlinelibrary.wiley.com/doi/10.1111/j.1095-8339.2001.tb02371.x/pdf | URI: | http://hdl.handle.net/10261/29840 | DOI: | 10.1006/bojl.2000.0360 | ISSN: | 1095-8339 |
