Slim, P.A.; Metzing, Detlev


The Mossy Stonecrop (Crassula Tillaea, Crassulaceae), a very rare species in Germany, was found for the first time on the East Frisian Wadden Sea Island of Norderney in 2017. The massive presence of the species on Norderney is discussed in relation with the current spread of the species and the colonization of new habitats.
