In Paraguay the use of medicinal plants is a very common custom. In this context we find Aloe vera, a cultivated species widely used in our country. However, it has been seen that instead of this species, two other species are marketed under the name A. vera: A. arborescens and A. saponaria. Therefore, the objective of this work was to describe the differential morphological and anatomical characters of the leaves of A. vera, A. arborescens and A. saponaria. For the aforementioned determinations, fresh leaves were taken from the three species grown in the Acclimatization Garden of the Faculty of Chemical Sciences of the National University of Asunción. For anatomical analysis, freehand cuts and epidermis lifting were performed. The differential morphological characters referred to the size and color of the leaf, in the anatomy the presence of raphides and shape of the chlorophyll cells were the differential characters. These morphoanatomical data constitute the first reports for these three Aloe species cultivated in Paraguay and will serve to differentiate the medicinal species A. vera from these two substitutes.
