It is widely distributed through Latin America from Mexico to Argentina, as well as from the West Indies.

Marsilea ancyclopoda is a floating aquatic herb forming dense colonies on the surface of the water. Petioles are up to 18 cm long, densely pubescent. Pinnae (leaflets) are 4, palmately arranged like Trifolium, up to 17 mm across and about the same distance long. Sporocarps are nodding, below the level of the stems (this being the only species in the genus with this character), covered with a pelt of shaggy hairs.[2][6][7]
