Cariology, anatomy, floral biology, and ecology are used in an intent to revise the genus Zannichellia. Six species are recognized, grouped in two sections: sect. Zannichellia, with Z. palustris L., Z. pedunculata Reichenb. And Z. major Boenn ex Reichenb., polyploids with male and female flowers in a same node and short stamens with bilocular anthers, and sect. Monopus Graebner, with Z. obtusifolia Talavera, Garcia-Mur. & Smit, Z. contorta (Desf.) Chamisso & Schlecht. and Z. peltata Bertol., diploids, with male and female flowers in different nodes and long stamens with tetralocular anthers. A key of the species is provided together with the correct names, synonymy, description, distribution and studied material for each recognized species. A new species, Z.obtusifolia, is described
