Cymopterus
Cymopterus is a genus of perennial plants in the family Apiaceae native to western North America. They are commonly known as the springparsleys.[1] They are mostly stemless, taprooted perennial herbs with leaves at ground level and flowering scapes bearing yellow, white, or purple flowers.[2]

Systematics
The taxonomy of this genus is confused even after many decades of study.[3] Authors have organized it in different ways, sometimes including several closely related Apiaceae genera within it, as the delimitations of the genus and its relationship with others are unclear.[3] It is very polyphyletic, and its limits are not well supported by evidence.[3] 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.[4]
There are perhaps 35[5] to 50[2] species in the genus, but the count changes constantly.
