Abstract
Justicia Linnaeus (1753: 15) is the largest genus of Acanthaceae (Wasshausen 2002). It comprises about 600 species (Graham 1988), distributed throughout the tropics and subtropics of both hemispheres, extending into the temperate regions of North America, with one species found as far north as Quebec in Canada (Wasshausen 1992a). In Brazil, the genus is represented by 128 species (Profice et al. 2015). Among them, Justicia andersonii Wasshausen (1992b: 666) is an illegitimate name, as it is a later homonym of J. andersonii Ramamoorthy (1976: 551). Therefore a new name, J. wasshausenii, is proposed as a replacement name for J. andersonii.
