Een nieuwe groeiplaats van de Pilvaren (Pilularia globulifera L.) in de Nederlandse duinen

Until now Pilularia globulifera was restricted, as far as it concerns its coastal distribution, to a few localities on the island of Terschelling. Recently, a tiny population was discovered in the non-calcareous dunes near Schoorl (prov. Noord-Holland). The plants grow in a shallow pool together with Littorella uniflora and Scirpus setaceus.
