|discussion=<p><i>Oclemena ×blakei</i> is the widespread, frequent, mostly F1 hybrid between <i>O. acuminata</i> and <i>O. nemoralis</i>, which has been confirmed by morphologic, chemical (R. B. Pike 1970; L. M. Hill and O. M. Rogers 1970, 1973; L. Brouillet and J.-P. Simon 1981), and isozyme data (Brouillet and Simon 1980). Hybrid populations also often include backcrosses to both parents as well as later generation hybrids and introgressed parental individuals. Hybrid clones may survive in areas where neither parent is found today. Some reports of this hybrid are misidentified <i>Eurybia radula</i>, which it superficially resembles.</p>
