*So taxonomists are in a bit of a scuffle about what genus to put flat-topped goldenrods in. As flat topped-goldenrods can hybridize with each other but not with other goldenrods, some have put them in Oligoneuron. As much as it would streamline my photo organization to have all the goldenrods together when alphabetized, several sources I respect have sided with the splitters. I bow to their expertise.
