             This figure shows histograms of the relative fluorescence intensity (corresponding ploidy level) of embryo and endosperm nuclei isolated from
             seeds. The upper right corner displays the interpreted ploidy level origins of the embryo and endospermꎬ represented as: ploidy of the egg cell +
             ploidy of the pollen (if involved) / ploidy of the central cell nucleus + ploidy of the pollen (if involved). A. Elatostema oblongifoliumꎻ
             B. E. cyrtandrifoliumꎻ C. E. atrovirideꎻ D. E. dissectum.
