Dispersal across southern Iberian refugia? Integrating RAPDs, sequence data and morphometrics in Armeria (Plumbaginaceae)

A southern Spanish massif (Tejeda/Almijara range, Málaga province, SE Spain) has been previously identified as a contact zone for genotypes of a rare taxon, Armeria villosa subsp. bernisii, and a frequent one, A. filicaulis, based on (1) the discovery of a species-independent geographically structur...
