Abstract

The occurrence of eight biflavones belonging to the biluteolin series, the apigenin-luteolin series and the 2,3-dihydro-biluteolin series, and one monomeric flavone with an acid group, was investigated in six taxa ofBartramia with emphasis on sect.Ithyphyllae. The variation of biflavone profiles contributes to the characterization of theBartramia species studied; substitution patterns signalize relevance also on the sectional level. Based upon the flavonoid composition,Bartramia afro-ithyphylla is suggested to be transferred from sect.Ithyphyllae to sect.Bartramia of the genusBartramia.
