Anatomy and histochemical localization of lipid secretions in Brazilian species of panicum sect. Lorea (poaceae, panicoideae, paniceae)

This paper constitutes the first report of the chemical nature, and histochemical localization of secretions in Brazilian species of Panicum L. sect. Lorea Zuloaga (Poaceae, Panicoideae, Paniceae); the study also includes an anatomical analysis. Lipid secretions were found in leaf sheaths and ligula...
