| Abstract: | Four populations each of Plummera floribunda and P. ambigens were examined for flavonoid content. Six compounds were isolated and identified as flavone and flavonol aglycones and flavonol glycosides. In all cases, both taxa were found to be identical in flavonoid content. Plummera was then compared to other genera in the subtribe Gaillardiinae. At the present time, it is the opinion of the author that Plummera is very closely related to, but not congeneric with Hymenoxys. |
