SYSTEMATICS OF GRATELOUPIA FILICINA (HALYMENIACEAE, RHODOPHYTA), BASED ON rbc L SEQUENCE ANALYSES AND MORPHOLOGICAL EVIDENCE, INCLUDING THE REINSTATEMENT OF G. MINIMA AND THE DESCRIPTION OF G. CAPENSIS SP. NOV. 1
Grateloupia filicina (C. Agardh) Lamouroux, originally described from the Mediterranean Sea, has long been considered a textbook example of a marine red alga with a cosmopolitan distribution. An rbc L‐based molecular phylogeny, encompassing samples covering the entire geographic distribution of the...
