New cover photo on Annals of Botany

During the summer of 2016, Dennis and I made a series of experiments on Glyceria fluitans which we, in fact, first thought was Catabrosa aquatica (check out the YouTube vdo). G. fluitans has superhydrophic leaves but the abaxial side becomes hydrophilic so that it floats on the water surface at high water levels. The cover photo on Annals of Botany shows the small droplets of water that forms on the adaxial surface of a floating leaf.
