Taxonomy

The taxonomy of this genus was described as confused in 2004, even after many decades of study.Sun, F. and S. R. Downie. (2004)
A molecular systematic investigation of Cymopterus and its allies (Apiaceae) based on phylogenetic analyses of nuclear (ITS) and plastid (''rps16'' intron) DNA sequences.
''South African Journal of Botany'' 70(3), 407-16. Authors have organized it in different ways, sometimes including several closely related Apiaceae genera within it. Genera recently segregated from ''Cymopterus'' include '' Vesper'', six plants with morphological characters that are well-defined and easily separated from ''Cymopterus''; the group has been separated before, but was reintegrated during repeated reorganizations of the genus.Hartman, R. L. and G. L. Nesom. (2012)
