Foliar flavonoid aglycones of the genus Keckiella (Scrophulariaceae)

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 der...
