The miscellaneous-type of bluing in rose petals (YASUDA and KIKUCHI, 1978) was re-examined using the following five cultivars: Cardinal de Richelieu, Blue Boy, Reine des Violettes, Shigyoku, and Samurai. The massive structures appearing in the epidermal cells of their petals showed striking similarity to the anthocyanophore-like structure in some rose petals which was reported by YASUDA in 1974b, 1976 and 1979 at three points: 1) staining features both with ruthenium red and safranine, 2) developmental process, 3) behaviors against weak acids. From these results, it was proposed that the bluing pattern exhibited in such roses as five cultivars mentioned above should be separated from the miscellaneous-type as a new group of bluing, an anthocyanophore-type.
