Populations of Armeria maritima (Mill.) Willd. collected in the South and in the North of the Netherlands are very different from each other. The Southern (Zeeland and Noord-Brabant) populations typically belong to ssp. maritima. The populations from the North (Noord- Holland and Friesland) must be referred to ssp. intermedia in which atypical forms intermediate between the atlantic ssp. maritima and the north-continental ssp. elongata are put together. The occurrence of ssp. intermedia is not related to particular ecological conditions. The ratio between “maritima” and “elongata” characters does not show a gradual trend from ssp. maritima to ssp. elongata along the coasts from the island of Texel to Denmark.
