EFT and curvature analysis in a papillose-type seed. Lateral view of a seed of S. perlmanni with the EFT curve superimposed in green and the corresponding curvature values plotted. The EFT curve shown resulted from 189 points taken along the silhouette and 74 harmonics, following the protocol published [20]. The numbers indicate the correspondence between individual tubercles and their curvature values. The program that provides the EFT curve contains the algorithm to obtain and represent the curvature values along it (see Supplementary Materials). This is a papillose-type seed, with tubercles of varied shape disposed unevenly at the seed surface. The maximum and minimum curvature values correspond to particular tubercles. Bar represents 1 mm.
