Abstract

The anatomy of roots, stem, leaves and inflorescence axis of Orectanthe sceptrum (Xyridaceae) will be studied for a comparative approach in the family. Since Orectanthe includes only two species with restricted distribution, this study will allow characterizing the genus, supporting this placement in the subfamily Abolbodoideae. With this purpose, permanent and semi-permanent slides will be confectioned for the light microscopy study. Cross and longitudinal sections will be made with razor blades in the basal, median and apical regions of the vegetative organs and inflorescence axis, and will be stained with basic fuchsin and astra blue. Additional sections will be made on a rotative microtome and stained with periodic acid-Schiff (PAS) and toluidine blue. The results will be analyzed, interpreted, documented with photomicrographys and discussed in a taxonomic context. (AU)
