• Abstract: Foliar flavonoid aglycones consist of luteolin and 6-hydroxyluteolin in five species of Keckiella. exceptional species are K. cordifolia, which contains only luteolin, and K. ternata, which contains the flavonols quercetin and kaempferol. These exceptional species are bird-pollinated and exhibit a derived morphology. Their flavonoid constitutions are proposed to be derived as well.
