Evidence for two genetic groups within the arctoalpine sedges Carex bicolor All. and C. atrofusca Schkuhr (Cyperaceae)

C. bicolor and C. atrofusca are sedge species characteristic for arctoalpine habitats. They have almost circumpolar distributions; they are found in Europe, Northern Asia, and North America, as well as in Middle Asia (C. atrofusca). We hypothesized that certain genetic and morphological differences...
