• Resumen

  • Verbena incompta, of presumed South American origin, is reported as a naturalised but overlooked xenophyte in Italy and Spain. The affinity of the species is discussed, emphasising on its separation from the related V. bonariensis and V. brasiliensis in V. series Pachystachyae, and ecological and chorological notes are added. The three species are illustrated by digitised representative herbarium specimen.
