The floristic composition and the vegetation of the La Gallega basin (Morropón, Piura) were studied. The plants were collected between 165 and 3,100 masl. The altitudinal ranges of the different vegetation floors were registered. The total amount of collected species belong to 56 families, being Asteraceae, Fabaceae, Lamiaceae and Solanaceae, the best represented. Species such as Acacia macracantha, Cordia lutea, Eriotheca discolor and Erythrina edulis, were those of greater altitudinal distribution. La Gallega basin also presents a great diversity of ecosystems composing 6 vegetation floors: columnar cactus and dry forest, deciduous forest, evergreen forest, shrubby and herbaceous vegetation, riverside mountain vegetation and low shrub vegetation.
