The marine algae of the eastern border counties of Scotland

During the visit of the British Phycological Society to Dunbar from 23 to 30 August 1972, algae were collected from shores in East Lothian, Berwickshire and the northern tip of Northumberland.These areas were widely collected in the past, most notably by Batters (1890) and Traill (1890), but in recent years only a few limited collections have been made (Jones, 1960;Johnston, 1972;Whittick, 1969).The species identified from the 1972 collections are listed below in alphabetical order within the major classes.The taxonomic nomenclature follows that of Parke & Dixon (1968) and the zones occupied by the algae are described using the terminology of Lewis (1964).For brevity, fruiting records have been represented by the following symbols: Male gametangia O Unilocular sporangia 2 Female gametangia [] Plurilocular sporangia Carposporophytes A Propagulae @ Tetrasporangia • Monosporangia • Parasporangia The following authorities were responsible for identification in the classes: Chlorophyceae --Dr E.
