Analysis of the geographic distribution of the Prosopis complex (Leguminosae, Mimosoideae) in North America
The geographic distribution of the North American species of the Prosopis-complex is illustrated and discussed. Out of the total of 10, 3 species belong in the section Strombocarpa, 6 in the section Algarobia and one in the genus Prosopidastrum, 3 taxa considered in Burkart's (1976) taxonomic t...

| description | The geographic distribution of the North American species of the Prosopis-complex is illustrated and discussed. Out of the total of 10, 3 species belong in the section Strombocarpa, 6 in the section Algarobia and one in the genus Prosopidastrum, 3 taxa considered in Burkart's (1976) taxonomic treatment as parallel evolutionary lines. lt is concluded that the joint picture given by the distribution areas suggests a considerable antiquity in terms of permanence of the group in arid North America. On the other hand, the presence of P. juliflora in Central America and in northern South America is interpreted as an indication of a transequatorial migration route and not as the point of departure of a convergent evolution in dry areas on both sides of the tropical belt. |

Out of the total of 10, 3 species belong in the section Strombocarpa, 6 in the section Algarobia and one in the genus Prosopidastrum, 3 taxa considered in Burkart's (1976) taxonomic treatment as parallel evolutionary lines. lt is concluded that the joint picture given by the distribution areas suggests a considerable antiquity in terms of permanence of the group in arid North America. On the other hand, the presence of P. juliflora in Central America and in northern South America is interpreted as an indication of a transequatorial migration route and not as the point of departure of a convergent evolution in dry areas on both sides of the tropical belt. Se ilustra y se discute la distribución geográfica las 10 especies norteamericanas del complejo Prosopis, de las que 3 pertenecen a la sección Strombocarpa, 6 a la sección Algarobia y una al género Prosopidastrum, grupos que, de acuerdo con el trabajo monográfico de Burkart (1976), representan 3 líneas evolutivas paralelas. Se concluye que, vistas en su totalidad, sus áreas sugieren una considerable antigüedad en términos de la permanencia del conjunto en Norteamérica árida. Por otra parte, la presencia de P. juliflora en Centroamérica y en la porción septentrional de Sudamérica se interpreta como indicio de una ruta migratoria transecuatorial y no como punto de partida una evolución convergente en zonas áridas a ambos lados del cinturón tropical.
