a Mean brightness-normalized reflectance (represented as a percentage) and b coefficient of variation (CV) of reflectance values for the four M. polymorpha Hawaii Island varieties and Oahu incana. See Fig. SI 2 for reflectance prior to brightness-normalization. c Spectral separability of all Hawaii Island and Oahu genotypes. Spectral separability was calculated for each wavelength (Eq. 1). Higher values indicate less spectral overlap. See Table 3 for average SSI values
