|discussion=<p><i>Rubus trivialis</i> is distinguished from other species of <i>Rubus</i> by its frequently glandular-bristly and generally creeping stems, abundant recurved prickles, and typically persistent or semipersistent, lustrous primocane leaves with relatively narrow leaflets. Although emerging primocanes typically reach to 30 cm above the ground, vigorous plants can have new primocanes standing erect to 70 cm that later fall to the ground or onto adjacent vegetation as they continue to enlarge. L. H. Bailey (1941–1945) believed that there was no clear separation between members of sect. Persistentes Fernald (referred to by Bailey as sect. Verotriviales [illegitimate sectional name for <i>R. trivialis</i> and associated species]) and sect. Procumbentes (by Bailey as sect. Flagellares; including <i>R. flagellaris</i> and related species). All characteristics that he recognized for distinguishing sect. Persistentes from sect. Procumbentes are often present in the latter, with the exception of hispid-setose stems, and glabrous plants of <i>R. trivialis</i> are difficult to distinguish from some plants of <i>R. flagellaris</i>; to include the latter species within the former would be reasonable.</p><!--
