“…and P. lychnitis L. with yellow flowers. Despite this apparent simplicity, taxonomy of the two yellow-flowered taxa has been a matter of controversy since the early 20 th century apparently due to hybridization and introgression (e.g., Pau, 1918;Mateu, 1986;Rivas-Martínez & al., 1991). Phlomis lychnitis is distributed across the Iberian Peninsula and southern France (Bòlos & Vigo, 1995) and hybridizes with P. crinita wherever their distribution ranges overlap in southern and eastern Spain (Andalusia and Levante, respectively).…”

Systematic and evolutionary relationships within the diploid Western Mediterranean Phlomis crinita/lychnitis complex remain controversial apparently due to hybridization and introgression. This study examines patterns of sequence variation in the nuclear ribosomal DNA (ITS region) and three non‐coding plastid DNA regions (trnH‐psbA, trnT‐trnL and atpB‐rbcL) in this complex in an aim to clarify whether hybridization, introgression or lineage sorting resulting from recent diversification is mainly responsible for poorly understood relationships. Information recovered from nuclear and chloroplast markers was found to be strongly incongruent. Phylogenetic analysis of inferred nuclear ITS ribotypes is consistent with previous morphometric and taxonomic results in distinguishing two sister lineages, P. crinita s.l. and P. lychnitis. In addition, the high number of additive polymorphisms detected in ITS sequences suggests the sharing of ancestral variability and local patterns of gene flow within the complex. In contrast, the pattern of chloroplast haplotype variation is geographic rather than taxonomic, which might be caused by low mutation rates combined with frequent instances of interspecific hybridization. To integrate the apparently discordant plastid and nuclear evidence, we suggest that both lineage sorting and horizontal transfer have been involved. Even though pinpointing cases due to either phenomenon is difficult, the available data provide evidence of two sister lineages where hybridization events can be identified despite the inheritance of ancestral polymorphisms.

“…Almost all the omissions mentioned will be corrected with the future European Network of Protected Areas which, in its Sites of Community Interest (SCIs), includes all the selected localities (Orella et al, 1998), except for La Pandera, which will remain unprotected and will be the most prominent gap in the Natura 2000 Network. The analysis matches up the first eight selected localities by ResNet to the six chorological units established by Rivas-Martínez et al (1997) and Rivas-Martínez et al (2002) in the Baetic ranges. If the biogeographic work of Sainz-Ollero and Hernández-Bermejo (1985) is taken into consideration, the first four localities selected by ResNet correspond to the four different sectors proposed for the Baetic high mountains by these authors.…”

Abstract.-The Baetic mountains are a very important centre of plant diversity and endemicity. The current environmental legislation includes many of these localities. In order to assess the current reserves network and to propose a selection of protected areas, and to examine the biogeographic distinctiveness of that selection, we applied to the orophilous endemic flora a variety of algorithms (some of which were never used for Europe before) on the Baetic ranges. In order to preserve this natural heritage, it would be necessary to protect at least twelve massifs, considering the siliceous portion of Sierra Nevada as a great priority area. The most notable gaps in the legislation are the ranges of Gádor, Revolcadores and La Pandera. The selected localities were characterized by their great biogeographical distinctiveness. The distinctiveness of the obtained selections stresses their reliability and also emphasizes the suitability of the biogeographic researches of the flora of the Baetic ranges for conservation objectives.Key words : biodiversity hot-spot -phytogeography -plant conservation -plant endemism -Tabu search.Résumé.-Les montagnes bétiques sont un centre très important de diversité de végétaux et d'endémicité. La législation environnementale actuelle inclut plusieurs de ces localités. Afin d'évaluer le réseau de réserves actuel, le choix des secteurs protégés et d'examiner les particularités biogéographiques de ce choix, nous avons appliqué à la flore endémique de la haute montagne quelques algorithmes (dont certains jamais employés pour l'Europe) aux cordillères bétiques. Afin de préserver cet héritage, il serait nécessaire de protéger au moins douze massifs, la partie siliceuse de la Sierra Nevada etant un grand secteur prioritaire. Les lacunes les plus notables dans la législation sont les chaînes de Gádor, de Revolcadores et de La Pandera. Les localités choisies ont été retenues pour leurs grandes particularités biogéographiques. La particularitié du choix obtenu indique son ajustement et montre la valeur des investigations sur la flore des montagnes bétiques pour des objectifs de conservation.Mots clés : hotspot de biodiversité -phytogéographie -conservation -endé-misme -Tabu search.

“…En nuestra metodología hemos tomado como válida la última propuesta al respecto de RivasMartínez (2011), que considera los territorios de las sierras de Baza y Filabres como integrantes del subsector Orofilábrico-Bastetano, perteneciente al sector Accitano-Bastetano (antes Guadiciano-Bacense) de la provincia Bética, diferenciándose dos distritos en función del carácter basófilo y acidófilo de la vegetación, como son el Serrano-Bastetano y el Serrano-Filábrico respectivamente. Esta propuesta incorpora al sector Accitano-Bastetano los territorios filábricos de la unidad montañosa Baza-Filabres como distrito Serrano-Filá-brico, hasta hace poco incluidos dentro del sector Nevadense, tal y como en su momento determinaron Rivas-Martínez et al (1997), sector Nevadense que el mismo autor define exclusivamente para Sierra Nevada en los nuevos planteamientos; esta separación de los territorios serrano-filábricos del sector Ne-vadense se realiza a pesar de que se aprecien ciertas coincidencias con éste debido a la naturaleza muy parecida del sustrato. Uno de los argumentos que utiliza este autor para la nueva sectorización es la existencia de la serie de vegetación recientemente descrita Genisto-Cytisetum nevadensis en el piso oromediterráneo seco superior de la zona esquistosa de Baza y Filabres, en la que, posiblemente, debido a fuegos y pastoreos ancestrales han desaparecido casi por completo los enebros rastreros (J. hemisphaerica), cuya existencia abundante correspondería a la facies climácica (Rivas-Martínez, 2011), tal y como hemos podido comprobar en campo, y que bajo las condiciones climáticas actuales no tienen cabida.…”

INTRODUCCIÓNEn el contexto de la Cordillera Bética, la Sierra de Baza conforma una isla climática y biogeográfica que actúa como centro destacado de especiación y refugio para la flora. La fitodiversidad vegetal del macizo, resultado de sus particulares evolución paleo-histórica y características mesológicas, se ha visto alterada por la profunda humanización del medio natural y la antigua configuración de un territorio con poblamiento milenario. La conjunción de estos factores dificulta la interpretación del paisaje vegetal y la sistematización de las actuales comunidades que lo forman (mezcla de etapas climácicas -y paraclimácicas-con estadios seriales de sustitución) en el seno del Parque Natural de la Sierra de Baza declarado en 1989.El conocimiento sobre la vegetación de esta montaña, tradicionalmente desarrollado desde la Biología y, en concreto, desde la Botánica, ha alcanzado un nivel acorde con su importancia biogeográfica y fitogeográfica. Sin embargo,
