Seaweeds of the Greek coasts: Rhodophyta: Ceramiales

Abstract

       An updated checklist of the red seaweeds (Rhodophyta) of the Order Ceramiales of the Greek coasts is provided, based on literature records, critically reviewed from present-day taxonomic and nomenclatural aspects. The total number of genera, species and infraspecific taxa currently accepted is 60, 118 and 2, respectively. The occurrence of each taxon in the North Aegean, South Aegean and Ionian Seas is given. Knowledge gaps are pointed, with 70 taxa pending confirmation of their presence marked. Moreover, 15 excludenda and 20 inquirenda taxa are briefly discussed. In this paper is given an updated base of the Ceramiales taxa occurrence in Greece, needed for future targeted seaweed. studies.
