In this paper, we report the presence of densely distributed nanopillar structures with grooved edges on the adaxial leaf surface of Annona squamosa. The hierarchical roughness contributes to the observed surface hydrophobicity with strong water droplet adhesion which approaches the petal effect. Th...
