Abstract Two species ofPinguicula (P. submediterranea andP. mundi) are newly described from the south and east of the Iberian Peninsula. We analysed morphometric, cytogenetic, RAPD, ecological, and breeding system data to support the distinctness of these taxa.Pinguicula submediterranea andP. mundi are both hexaploid (2n = 48), a chromosome number previously not reported for the genus. Biometric, cytogenetical and molecular results distinguishP. submediterranea andP. mundi from otherPinguicula species, and from each other.Pinguicula mundi is predominantly outbreeding, whereasP. submediterranea both inbreeds and outbreeds.Pinguicula submediterranea andP. mundi appear to be isolated reproductively, although gene flow between the allopatricP. submediterranea andP. mundi is unlikely. BothP. submediterranea andP. mundi are threatened with extinction because suitable habitats are diminishing in size, or even disappearing, due to current aridity in the region.
