Villarsia is a genus of aquatic flowering plants in the family Menyanthaceae. The genus is named for the French botanist Dominique Villars (1745-1814). Villarsia are wetland plants with basal leaves. The inflorescence is a branched panicle with numerous flowers. Flowers are five-parted, either yellow or white, and the petals are adorned with wings.
