Cymopterus glomeratus (Fendler's spring-parsley, Fendler's cymopterus, plains springparsley), now including Cymopterus acaulis, is a flowering plant. This plant is an aromatic plant of the family Apiaceae, a family of commonly known as the “celery, carrot, or parsley” family. The genus name comes from the Greek word, “Cyma” which means “wave” and “Pteron” which means “wing”, and combines to form the genus “Cymopterus”.

Incorrectly known as Cymopterus acaulis, a multivariate and phylogenic analysis of this plant species found that there were “not geographically distinguishable based on their overlapping or adjacent distributions” and proposed to recognize as Cymopterus acaulis and all of its varieties as one species as Cymopterus glomeratus. There were five varieties of Cymopterus acaulis, which include var. C. acaulis, var. C. fendleri, var. C. greeleyorum, var. C. higginsii, and var. C. parvus.
