|discussion=<p>L. Brouillet and J. C. Semple (1981) summarized the morphologic, chemical, cytological, and hybridization data on <i>Solidago ptarmicoides</i> and concluded that, except for the white rays, it is a typical member of sect. Ptarmicoidei. The species hybridizes with <i>S. rigida</i>, <i>S. ohioensis</i>, <i>S. riddellii</i>, and perhaps other goldenrods. It is not known to hybridize with any species of aster (regardless of genus); the supposed <i>Aster</i> × <i>Solidago</i> hybrids are the basis of all reports of intergeneric hybrids in the literature. Horticultural hybrids involving <i>S. ptarmicoides</i> and other <i>Solidago</i> species have been treated as S. ×luteus (M. L. Green ex Dress) Brouillet & Semple (×Solidaster luteus M. L. Green ex Dress). <i>Solidago</i> ×bernardii B. Boivin [Oligoneuron ×bernardii (B. Boivin) G. L. Nesom] is the formal name applied to <i>S. ptarmicoides</i> × <i>S. riddellii</i> hybrids; those have cream rays. <i>Solidago</i> ×lutescens (Lindley ex de Candolle) B. Boivin [Diplopappus lutescens Lindley ex de Candolle; D. albus var. lutescens (Lindley ex de Candolle) Hooker ex Torrey & A. Gray; <i>Aster</i> lutescens (Lindley ex de Candolle) Hooker ex Torrey & A. Gray; A. ptarmicoides var. lutescens (Lindley ex de Candolle) A. Gray; Oligoneuron ×lutescens (Lindley ex de Candolle) G. L. Nesom] applies to hybrids between <i>S. ptarmicoides</i> and <i>S. rigida</i> or <i>S. riddellii</i> from the prairies; these also have cream colored rays.</p>
