Even though ferns diverged from the seed plants about 360-430 million years ago, most extant ferns originated from recent Cenozoic radiation events. Recently diverged groups often consist of species exhibiting subtle morphological differences with frequent naturally occurring hybrids, resulting in a poorly understanding of these groups’ diversity The rapid decline of biodiversity emphasizes the need to character… Show more
