AB The genus Erophaca comprises a single herbaceous perennial species with two subspecies distributed atopposite ends of the Mediterranean region. We used nrDNA ITS to investigate the phylogeny of the genus,and AFLP markers (9 primers, 20 populations) to establish the genetic relationship between subspecies,and among populations at each side of the Gibraltar Strait. According to nrDNA ITS, Erophaca is monophy letic, old (Miocene), and sister to the Astragalean clade. Life form attributes and molecular clock esti mates suggest that Erophaca is one of the many Tertiary relicts that form part of the presentMediterranean flora. Within the occidental subspecies, European plants are clearly derived fromNorth-African populations (Morocco) which, despite being rare on a regional scale, present the highestgenetic diversity (as estimated by private and rare fragment numbers). In general, genetic diversitydecreased with increasing distance from Morocco. AFLP and nrDNA ITS markers evidenced that the East ern and the Western subspecies are genetically distinct. Possible causes for their disjunct distribution arediscussed
