S ummary Chromatographic analysis of the floral pigments of species of the genus Papaver revealed the presence of cyanidin and pelargonidin derivatives and in addition yellow compounds which were not anthocyanins. The distribution of these pigments among the poppy species supports Fedde's division of the genus into sections, and suggests an affinity between the sections Pilosa and Scapiflora. The pigments of three interspecific hybrids showed the biochemical versatility of the less versatile parent. The anthocyanins of petals and stamens frequently differed and the bases of petals normally contained petal and stamen pigments in mixture. High concentrations of cyanidin pigments were not found in the same floral parts as either yellow pigments or high concentrations of pelargonidin derivatives.
