abstract = {The clover fern Marsilea azorica was described in 1983 from the isolated Azores archipelago in the Northern Atlantic, where it is restricted to a single roadside pond. Thought to be an extremely local endemic, it was subsequently listed as a conservation priority species for the Azores, Macaronesia, and Europe, included as ?critically endangered? on the IUCN Red List, and as ?strictly protected? species by the Bern Convention and the European Union?s Habitats Directive. However, in this paper, we present morphological and molecular data (rbcL gene, rps4 gene, rps4-trnS spacer and trnL-trnF spacer sequences), which demonstrate that M. azorica is conspecific with M. hirsuta, a species native to Australia but widely cultivated and locally invasive in the Southern United States. Based on our DNA data, we conclude that the Azorean plants are most likely a recent introduction to the Azores from Florida. We recommend removal of the Azorean Marsilea from conservation priority lists. While there is so far no evidence that the small existing population threatens native species, further spread in the Azores should be prevented.}
