Resumen:
In this study, foliar and petiole anatomy of several genera wits compared to determine whether there are characteristics that call be used to reevaluate the circumscription and taxonomic position of Hamelieae (Rubiaceae). Our sample included a total of,36 species, which were sectioned using conventional embedding and staining methods. Front these species, 23 represented six of the seven genera of Hamelieae sensu Robbrecht; Syringantha Standl. was included in order to reevaluate its putative inclusion within Hamelieae. For comparative purposes, the sample also included representative species of tribes Psychotrieae (Rubioideae), the Portlandia informal group (Cinchonoideae), and Gardenieae (Ixoroideae). Our results indicated that foliar and petiole anatomy contained taxonomic information that Call be used in systematic studies. Members of Hamelieae shared the following characters: cuticle more [hall 3 pro, dorsiventral mesophyll, a single palisade parenchyma cell layer, loose spongy pare
