Valor taxonómico del polen en Scrophulariaceae sensu lato Sosa, María de las Mercedes Salgado, Cristina R. Morfología del polen sistemática euripolínico Scrophulariaceae. Pollen morphology systematic eurypalynous Scrophulariaceae. Taxonomic value of pollen in Scrophulariaceae sensu lato. This paper is result of a study of pollen morphology of 32 species belonging to 19 genera of Scrophulariaceae sensu lato. A comprehensive record of available information on the pollen morphology in this group in order to analyze the relationships between palynological variables and the current systematic classification was also conducted. Pollen grains are monads, radially symetric and isopolar, the sizes vary from small (11 ?m) to medium (51 ?m), predominately spheroidal (P/E = 1), sometimes suboblates (P/E = 0.76), oblate-spheroidal (P/E = 0.95),prolates (P/E = 1.63) and perprolates (P/E = 2.63). They are inaperturates, 3- (4-5) colpates, 3- (4-5) colporates, spiraperturates 2-8 syncolpates, 3-colpo-diploporates and pantoporates grains. The exine may be semitectate (retipilate, reticulate or striato-perforate) and tectate (psilate, foveolate, perforate, scabrate, rugulate, verrucate, granulose, striate, echinate). Statistical analysis was performed based on the data matrix of the palynological characters of the 32 species studies in addition to bibliographic references of 140 genera and 218 species belonging to Scrophulariaceae sensu lato. The cluster analysis (UPGMA), confirmed that palynomorphological differences support the current systematic classification. Este trabajo es el resultado del estudio palinomorfológico de 32 especies pertenecientes a 19 géneros de Scrophulariaceae sensu lato. Además se realizó un registro exhaustivo de la informaciónbibliográfica existente sobre la morfología polínica con el objetivo de analizar las relaciones entre las variables palinológicas y la clasificación sistemática actual. Los granos de polen analizados son:mónades, radiosimétricos e isopolares, de tamaño variable desde pequeños (11 ?m) hasta medianos (51 ?m), predominantemente esferoidales (P/E= 1), a veces suboblatos (P/E= 0,76), oblato-esferoidales (P/E= 0,95), prolatos (P/E=1,63) y perprolatos (P/E= 2,63). Inaperturados, 3-(4-5) colpados, 3-(4-5) colporados, espiraperturados, 2-8 sincolpados, 3-diploporados y pantoporados. La exina puede ser semitectada (retipilada, reticulada o estriada perforada) y tectada (psilada, foveolada, perforada, escábrida, rugulada, verrugosa, granulada, estriada o equinulada). Se realizó un análisis estadístico en base a una matriz de datos, compuesta por los caracteres palinológicos de 32 especies estudiadas sumado a la recopilación bibliográfica de 140 géneros y 218 especies pertenecientes a Scrophulariaceae sensu lato. El análisis de agrupamiento (UPGMA), confirmó que las diferencias palinomorfológicas apoyan la clasificación sistemática actual.
