Quantitative Morphological and Molecular Divergence in Replicated and Parallel Radiations in Carex (Cyperaceae) Using Symbolic Data Analysis
Two species-rich lineages of Carex, C. sect. Phacocystis and the Vesicariae alliance, show a replicated and parallel radiation in the Northern hemisphere. Each group possesses a clade consisting of mostly boreal to arctic species and a second clade comprising more southerly distributed species. In t...
