Crassula helmsii (Kirk) Cockayne, een adventief op droogvallende, zandige oevers

Crassula helmsii, an amphibious species originating from temperate Australia and New Zealand, is recorded for the first time from the Netherlands. In 1995 and 1996 it has been found in a nature reserve near Breda. The authors suggest that it should be destroyed there in order to prevent that it becomes an invasive weed.
