In this article, superhydrophobic leaves of Cassia tora, Adiantumcapillus-veneris (ACV), and Bauhinia Variegate are reported for the first time,and the wettability of these leaf's surfaces was correlated with their surfacemorphology at micro and nanoscale. Field Emission Scanning Electron Microscopy(FESEM) images of the surfaces were used to get surface morphologicalinformation at the micro-nanoscale structures. A special drying method wasimplemented to ensure the minimal structural collapse of these surfaces underthe high vacuum of FESEM. FESEM images of Cassia tora leaves showed widelyspaced, low aspect ratio nano petals distributed on bumpy blunt micro features,responsible for high contact angle hysteresis and high roll angle measured onthe Cassia tora leaves. ACV leaves showed the presence of micron-scalespherical morphology made of nanoscale hair-like features. These hierarchicalre-entrant surface features generated a very high contact angle and lowroll-off angle. Leaves of Bauhinia variegate showed similar superhydrophobicand self-cleaning properties. However, surface features were different, whichconsisted of a higher aspect ratio and closely spaced nano petals uniformlydistributed over flat surfaces consisting of micro-scale ridges. Droplet impactstudies on these surfaces at different Weber numbers showed different behaviourdue to these different micro-nano features.
