3.4 Leaf surface wettability
The results of surface wettability at the area of interest of each
species (see Table 2 ) were summarized in Fig. 7 (seeFig. S1 for representative images). Leaf surface wettability
ranged from highly hydrophobic (90º < θC< 150º) to superhydrophilic (θC <
10º). We observed extremely fast hemiwicking (i.e. capillarity-driven
spread of liquid on a rough hydrophilic surface) in C. tecta(Video S1 ) and, to a much lesser degree, in C. ausensis(Video S2 ).
