|discussion=<p>Known from northeastern Vermont, <i>Rosa sherardii</i>, a Scottish introduction in the nineteenth century, is an erect, compact shrub often forming rhizomatous thickets. Sepals are spreading to erect and persistent after anthesis, auricles are 3–4 mm, bracts 16–21 mm, and stylar orifices 2.5 mm diam.</p><!--
--><p><i>Rosa sherardii</i> occurs frequently in northern England and Scotland, as does the closely allied <i>R. mollis</i>. <i>Rosa sherardii</i> and, undoubtedly, <i>R. mollis</i>, both recently identified in the flora area by A. V. Gilman, were brought to Vermont by Scottish immigrants who settled and farmed there (Gilman 2012).</p>
