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. 相似文献

The recent merger ofPlummera intoHymenoxys is followed here. The two previously recognized species ofPlummera are here treated as a single polymorphic species ofHymenoxys, H. ambigens, consisting of three varieties: var.ambigens from the Mescal, Santa Teresa, and Pinaleno Mountains of southeastern Arizona; var.floribunda from the Chiricahua, Dos Cabezas, Dragoon, Little Dragoon, and Mule Mountains of southeastern Arizona; and var.neomexicana described here from the Animas and Peloncillo Mountains of southwestern New Mexico. 相似文献
