Euastrum cerradense G.J.P.Ramos, C.E.M.Bicudo & C.W.N.Moura , nom. nov.

Replaced name: Euastrum rotundatum Kurt Förster & Eckert (in Förster) Hydrobiologia 23: 368, pl. 7: fig. 9; pl. 41: fig. 15. 1964, nom. illeg., non Euastrum rotundatum F.Gay ( Gay 1884: 58, pl. I: fig. 14).

Note: While Förster’s original description lacks an explicit designation of type, a single gathering was indicated “Rio das Femmeas bei Porta Azul (Goyaz)”, currently Tocantins State (ca. 13° S, ca. 48° W), which serves to validate the name (Art. 40.2). The new epithet refers to the Cerrado biome, the largest savanna-like region in South America , from which the species was collected .
