Abstract
A STUDY of anthocyanin-pigmented flowers of species of the genus Lathyrus revealed a correlation between blueness of petals and the presence of the flavonols quercetin and kaempferol1. It was suggested that these substances (which may be present as glycosides2) acted as co -pigments which modified the colour towards blue. In this communication evidence is presented from a study of the flowers of interspecific hybrids between the species of the section Clymenum3 which supports the above view. Three interspecific crosses yielded limited numbers of fully developed viable seeds, namely: L. articulatus L. × L. clymenum L., L. articulatus × L. ochrus DC. and L. clymenum × L. ochrus4,5.
