Anatomia floral de Barjonia erecta (Vell.) Schum. (Asclepiadaceae)

In the present work the authors present the study of the floral anatomy of the specie Barjonia erecta (Vell.) Schum. The following anatomical characteristics were observed in the floral segments: presence of bicollateral bundles in the pedicel and receptacle; collateral bundles in the corola tube, sepals, petals, anthers and gynostegium. In each carpel were observed 24-25 vascular bundles of which three are more developed: two are denominated secundary marginal and largest, the dorsal bundle. The coronas consist of ten parenchymatous segments whithout vascularization but presenting a papillose epidermis.
