Abstract: The genus Morrenia, in Argentine, is formed by five endemic species and ninenative ones. They are perennial herbs, shrubs and lianas that are characterized to presentlatex. M. odorata is used for its medicinal properties (galactogoga, antiinflammatory,tranquilizing) and nutritional ones (fruits). With the exception of few anatomical observationspublished by Cortadi et al (1999), other data are not known about the anatomy of the genus.In this work the primary structure of the vegetative organs of M. odorata is described.The stems have monostratified epidermis with apiculate stomata. The stele presents fourbicollateral bundles. Laticifers and idioblasts with druses are observed. In the roots theepidermis is monostratified, the diarch stele and the laticifers are in the cortex. The leavespresent monostratified epidermis, apiculate stomata, bicollateral bundles and laticifers. Threefoliar morphotypes in relation to the age of the leaf were differentiated and anatomicaldifferences among them were studied.Key words: Morrenia odorata, Asclepiadaceae; medicinal herb; morphoanatomy.
