Abstract
A new subspecies of the Betic-Riffean species Armeria filicaulis is formally described –subsp. alfacarensis– from crystalline dolomitic sands NE of Granada (SE Spain). Its representatives exhibit a consistent morphological combination of characters on the inflorescence and flowers that support its taxonomic recognition. This is shown by means of a multivariate morphometric analysis. In one of the sites of the new taxon, where it is sympatric with A. villosa subsp. bernisii, nuclear ribosomal ITS sequences reveal gene flow between the two species, which is congruent with RAPD data and chloroplast trnL-F haplotypes. It is discussed that gene flow detected is not responsible for the origin of the new subspecies but a recent event. According to this, a differentiated biological entity related to other forms of A. filicaulis inhabiting dolomitic sands in eastern Andalusia, existed previously to gene flow events. The patterns detected (and inferred events) in A. filicaulis throughout its area suggest that the compilospecies model fits the evolution of this species as does that in A. villosa (as reported elsewhere) although not as closely. Se describe una nueva subespecie de la bético-rifeña Armeria filicaulis, que habita en arenas dolomíticas cristalinas del nordeste de Granada (sudeste de España): subsp. alfacarensis. Su reconocimiento taxonómico se apoya en una combinación constante de caracteres relativos a la inflorescencia y flores, como se comprueba en el análisis morfométrico multivariante que presentamos. En una de las localidades donde vive la nueva subespecie de forma simpátrica con A. villosa subsp. bernisii, las secuencias de ITS del ADN ribosómico nuclear revelan flujo génico entre ambos táxones, lo cual es congruente con los resultados que se presentan de RAPDs y con los haplotipos detectados de secuencias cloroplásticas (trnL-F). Se argumenta que el flujo génico detectado no es responsable del origen de la nueva subespecie sino consecuencia de un suceso más reciente. De acuerdo con esta interpretación, con anterioridad al flujo génico aludido, existiría una entidad biológica diferenciada en la zona, afín a otras formas de A. filicaulis que habitan en arenas dolomíticas del este de Andalucía. Los patrones detectados en A. filicaulis a lo largo de su área de distribución, así como los procesos inferidos, sugieren que el modelo de evolución de esta especie se ajusta al de compiloespecie, tal como propusimos para A. villosa en otro trabajo, aunque no de forma tan patente.
