Solidago sect. Ptarmicoidei is a section of flowering plants in the genus Solidago.[1] They are sometimes considered a separate genus: Oligoneuron.[2][3] Like related species they are known as goldenrods. This section contains seven species of perennialherbs, all native to North America.[1][4][5] They are distinguished from other goldenrods by their corymbiform flowerheads, which are flat or rounded in profile and about as broad as tall or broader, for which they are sometimes called flat-topped goldenrods.[1][6][7]
