<p>This study is the first to report leaf resupination in <i>Paspalum saccharoides</i> Nees&#xa0;ex Trin., marking its first documented occurrence in the subfamily Panicoideae. The leaf blade undergoes a 90° twist which, combined with the species' decumbent growth habit, leads to a 180° inversion, positioning the abaxial surface upward. Field observations in Venezuela confirmed this characteristic in different populations. Anatomical analysis revealed notable features, including a higher stomatal density on the adaxial surface and the presence of large, colorless parenchyma cells on the abaxial side, both of which are inverted compared to typical <i>Paspalum</i> species. These traits, alongside recent phylogenetic studies, have potential implications for the species’ taxonomic classification, possibly supporting its recognition as a separate genus. This discovery provides new insights into the ecological and evolutionary adaptations of <i>P. saccharoides</i>, opening avenues for further research on leaf resupination in grasses.</p>
