Did you know?
Prairie dunewort was recognized as a separate species in 1986 after different-looking moonworts were discovered in Iowa prairies and sand dunes along Lake Michigan. They were overlooked before because they are so small and hard to see among grasses, come up very early in the spring, and are gone before the end of June. After examination of more specimens from around the country it was discovered that this species was also collected in Jamesville, NY, the easternmost population.
