E-mail: [email protected], [email protected] SUMMARY: The name Lavatera columbretensis, recently proposed for a hybrid growing in the Columbretes Archipelago (Castellón, E of Spain), is transferred to Malva. Additional data on nomenclature of other related taxa of ‘L. sect. Anthema’ and ‘L. sect. Axolopha’, are also reported. Key words: Lavatera, Malva, hybrids, Mediter- ranean islands, Spain. RESUMEN: Se transfiere al género Malva el nombre Lavatera columbretensis, recientemente descrito para un híbrido encontrado en el archipiélago de las Columbre- tes (Castellón). Además, se presentan datos complementarios sobre la nomenclatura de otros táxones de ‘L. sect. Anthema’ y ‘L. sect. Axolopha’, con él relacionados. Pala- bras clave: Lavatera, Malva, híbridos, islas mediterráneas, España.
