Setting conservation priorities in taxonomically complex groups is an especially difficult task. The seashore sedges of the Carex salina group (Cyperaceae) of the Russian White and Barents Seas form important parts of the coastal ecosystems and include species listed as rare and endangered. However, their taxonomy is poorly understood and supposed to be blurred by hybridization, also including the closely related C. aquatilis and possibly other species of sect. Phacocystis (C. bigelowii, C. nigra s. lat.). We address the taxonomic situation in the C. salina group in the Kola Peninsula with emphasis on taxa of supposed hybrid origin (C. salina and C. recta coll.). We analyzed 92 plants from 28 sites for 101 amplified fragment length polymorphisms (AFLPs) and 10 morphological characters. The plants referred to three supposedly "pure" species (C. aquatilis, C. paleacea and C. subspathacea) formed different extreme parts of the morphological and molecular variation. These species could be discriminated by a combination of morphological characters. The two taxa of proposed hybrid origin had extremely variable morphology and could not be clearly distinguished from each other or from the supposedly "pure" species. Our results demonstrate extensive gene flow between all taxa, suggesting that the entire C. salina group including C. aquatilis acts as a single large biological species.
