|discussion=<p>Occasional plants without feathery hairs identified as <i>Dryas ajanensis </i>subsp.<i> beringensis</i> are likely <i>D. incisa</i>.</p><!--
--><p><i>Dryas</i> crenulata Juzepczuk and <i>D. integrifolia</i> subsp. crenulata (Juzepczuk) Scoggan have been misapplied to <i>D. incisa</i>, for example, by A. E. Porsild and W. J. Cody (1980) and Cody (2000). <i>Dryas</i> crenulata is of eastern Siberia (B. A. Jurtzev 1984).</p>
