Galanthus elwesii Hook. f. in de provincie Utrecht

Galanthus elwesii Hook. f. was first found in the Netherlands in 1941. Up to now only two country seats are known where G. elwesii is still growing, one of them being in the province of Utrecht. This paper deals with the occurrence of four new localities in the province of Utrecht, where O. elwesii appears to be naturalized on two of them. The accompanying species on the natural localities are mainly characteristic of the Ulmion-Carpinifoliae vegetation, with sometimes a slight transsition to the Agropyro repentis-Aegopodietum podagrariae vegetation. Chromosome numbers counted are in accordance with those reported in the literature. The place in the Standard List of the Netherlands Flora is discussed. Based on the new data G. elwesii appears to belong to the Netherlands flora.
