Molecular phylogenetics supports widespread cryptic species in moonworts ( Botrychium s.s., Ophioglossaceae)
• Premise of the study: Previous phylogenetic studies of moonworts ( Botrychium sensu stricto (s.s.)) included few taxa from outside of North America. This low geographical representation limited interpretations of relationships of this group rich in cryptic species. With 18 out of 30 species in the...
