The study reported here was carried out at the SE coast of Ireland (Co. Wexford) during the summer of 1974. The SE coast of Ireland has a relatively rich maritime flora: 60% of the total number of Irish maritime species have been recorded here, and again 60 % of the total number of Irish maritime Atlantic and Atlantic-Mediterranean species. These phenomena can be explained from the great variety of habitats along the SE coast (rocky headlands, dunes, sandy and gravelly beaches, salt-marshes) and from climatic conditions (the SE of Ireland is the driest and the warmest part of the country).
