Popis: In this paper, the identity and degree of naturalization of Desmanthus (Leguminosae, Mimosoid clade) in the Canary Islands (Gran Canaria, Fuerteventura) and Cape Verde (Santo Antão, São Vicente) are critically re-assessed. The study of morphological features of the plant material sampled allowed to conclude that all specimens must be assigned to D. pernambucanus, instead of D. virgatus as previously thought. Previous records for D. virgatus from Macaronesia still require confirmation but are probably all erroneous. D. pernambucanus is well-established and the number of populations is increasing in the studied area. The species can be classified as an environmental weed or even as a transformer species in natural habitats, often barrancos. The results also show that the distinction between D. pernambucanus and D. virgatus is not always clear-cut and that for an accurate identification the study of living material usually is required.
