title: A history of discoveries and disappearances of the rare annual plant <i>Lythrum thesioides</i> M.Bieb.: new insights into its ecology and biology
abstract: Mediterranean temporary pools are threatened ecosystems that host a unique plant community, mostly composed of annual species with large and long-lived seed banks. The longevity of their seed bank, the scarcity of their habitat, the small size of their populations and the low frequency of above-ground vegetation result in a low probability of detection of these species. The discovery of new populations of such rare species are thus important for our understanding of the ecology of the temporary
