EZCURRA, Cecilia y DANIEL, Thomas F.. Ruellia simplex, an older and overlooked name for Ruellia tweediana and ruellia coerulea (Acanthaceae). Darwiniana [online]. 2007, vol.45, n.2, pp. 201-203. ISSN 1850-1699.
Ruellia simplex, the name of a species of Ruellia described from Cuba in 1870, is the oldest name for the neotropical species generally known as Ruellia tweediana, Ruellia coerulea and Ruellia malacosperma. Therefore Ruellia simplex has priority and reduces tha latter names to synonym. This species has an amphitropical distribution in the New World, being found in southern United States, Mexico and the Antilles, and in western Bolivia, southwestern Brazil, Paraguay, Uruguay, and northeastern Argentina.
