|discussion=<p><i>Rosa canina</i> occurs sporadically throughout Canada and the United States in disturbed areas. Shrubs lack rhizomes and have arching stems with paired or single curved infrastipular prickles all more or less uniform in length. Sepals (abaxially), stipules, petioles, rachises, pedicels, blades (abaxially, except some veins), hypanthia, and hips are all glabrous and most are also eglandular.</p><!--
--><p>W. J. Bean (1970–1988) cited <i>Rosa canina</i> var. corymbifera (Borkhousen) Rouy, <i>R. canina</i> var. dumetorum (Thuillier) Baker, and R. dumetorum as synonyms of R. corymbifera, and that treatment is followed here.</p><!--
--><p>Moderate evidence exists for the efficacy of powdered achenes and hip receptacles of <i>Rosa canina</i> to treat patients suffering from osteoarthritis, specifically of the knee and hip (K. Winther et al. 2005; C. Chrubasik et al. 2006).</p>
