ABSTRACT
This work aims to contribute to a better knowlodge about the Marsdenia loniceroides flower, with the objective of providing subsidies to taxonomy of the subfamily Asclepiadoideae. Data about the development and floral anatomy of this species is presented. It is analized the origin of the corona, translators and the structures situated between the sepals and corola tube. These structures are considered glandular emergences. Marsdenia loniceroides corona has staminal origin and it are not vascularizated. Translators (retinaculum and caudiculum) are originated by the cells secretory activity that covers the stylar head, and the glandular emergences are originated in sepals internal face. These aspects - corona’s and translators’ origin, emergences’ origin and its constitution are characteristics of this species. It must be emphasized that the other anatomic aspects correspond to the subfamily pattern. In this work the set consisted by corola tube and staminal tube is considered floral tube.
