Cymopterus

Cymopterus is a genus of perennial plants in the family Apiaceae native to western North America. They are commonly known as the spring parsleys and are edible. They are mostly stemless, taprooted perennial herbs with leaves at ground level and flowering scapes bearing yellow, white, or purple flowers.

==Taxonomy== The taxonomy of this genus was described as confused in 2004, even after many decades of study. 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. The number of accepted species has varied between about 50 to about 35.
