Cymopterus is a genus of perennial plants in the family Apiaceae native to western North America. They are commonly known as the spring parsleys^[2] and are edible. They are mostly stemless, taprooted perennial herbs with leaves at ground level and flowering scapes bearing yellow, white, or purple flowers.^[3]

Taxonomy

The taxonomy of this genus was described as confused in 2004, even after many decades of study.^[4] Authors have organized it in different ways, sometimes including several closely related Apiaceae genera within it.^[4] 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.^[5] The number of accepted species has varied between about 50^[3] to about 35.^[6][1]
