[email protected] ABSTRACT. A study on the leaf anatomy of Cordiera sessilis (Rubiaceae), a native medicinal shrub from Brazilian Cerrado was carried out to identify features that may be useful in species recognition. Leaves were collected, fixed and processed by usual techniques, and studied by light and electron microscopy. Quantitative analyzes of stomata and trichomes were performed. In addition to the typical anatomical characteristics of Rubiaceae leaves, two types of vascular patterns were identified in the petiole: in distal part, the vascular system is arranged cylindrically surrounded by sclerenchyma sheath and in proximal part the vascular system is arranged in U-shape coupled to sclerified cells.
