The biennial to short-lived wintergreen perennial Cochlearia officinalis L. s.l. (basic chromosome number x = 6) encompasses a group of closely related taxa that is difficult to delimitate morphologically. Despite a lack of distinct sets of discontinuous morphological characters, at least six numerically different cytotypes have commonly been recognized, and they have different ecologic distributions. Evolution of the wide ploidy level was likely brought about by hybridization and… CONTINUE READING
