We used five fruit traits for our analyses testing the existence of syndromes in Viburnum. The observed species values, differentiated into fruit color category, are displayed here: a lipid content, b moisture content, c pulp volume, d endocarp flatness (width/height ratio), and e fruit width. Each point indicates the measured value for a species. In f, we display the two main variables describing fruit color that are relevant to Viburnum: short-wave reflectance (reflectance in the blue region of the spectrum) and long-wave reflectance (reflectance in the red region of the spectrum)
