| Abstract: | Heterogaura is a monotypic genus of the tribe Onagreae of the Onagraceae. It is endemic to south western Oregon and California. Four flavonol glycosides, kaempferol 3-O-rhamnoside, quercetin 3-O-glucoside, quercetin 3-O-rhamnoglucoside and myricetin 3-O-glucoside, were found to occur in methanolic leaf extracts of each of the populations sampled. The presence of only flavonols is consistent with flavonoid analyses from other genera of the Onagreae, including Clarkia, the closest relative of Heterogaura. |
