Ganem, María Alejandra Luna, María Luján Giudice, Gabriela Elena Asplenium esporas morfología Argentina Asplenium spores morphology Argentina Palynological study in Asplenium species (Aspleniaceae) from Argentina. The genus Asplenium L. is represented in Argentina by about 38 species, being its habit terrestrial, saxicolous or ephiphytic. In this contribution we complete the palynological study of the genus in this country. The material was processed according to standard techniques for observation under light and scanning electron microscopes. The spores are monolete, the wall formed by the homogeneous exospore, with smooth surface, and the camerate and folded perispore. Two types of folds, winged and ridged, are registered. A variability in the density of the perforations in the outer layer of the perispore, and the margin and sculptural elements of the folds and in the areas between them, are also observed. Spores of analyzed taxa are described and illustrated with pictures using scanning electron microscope. El género Asplenium L. se halla representado en Argentina por cerca de 38 especies, siendo su hábito terrestre, saxícola o epífito. En la presente contribución se completa el estudio palinológico del género en este país. El material fue procesado de acuerdo a técnicas clásicas para su observación con microscopios óptico y electrónico de barrido. Las esporas son monoletes, la pared está conformada por el exosporio homogéneo de superficie lisa, y el perisporio camerado y plegado. Se distinguen dos tipos de pliegues: alados y lomados y se observa variabilidad en cuanto a la densidad de las perforaciones del estrato externo del perisporio, a los tipos de margen y los elementos esculturales de los pliegues y a las áreas entre pliegues. Se describen las esporas de los taxa estudiados y se ilustran con fotografías al microscopio electrónico de barrido.
