|discussion=<p>Southern limits of <i></i>subsp.<i> sayi</i> occur in the Rocky Mountains of Colorado, Black Hills of South Dakota, and algific slopes of talus or broken rock covering ice caves in northeastern Iowa, southwestern Wisconsin, Ice Mountain of West Virginia, and mountainous regions of New England where habitats similar to more northern ecosystems exist. Among these outlying populations, the density of stem prickles and aciculi often decreases and fertile branches rarely may be devoid of most armature. In central Canada and northward to Alaska, sepals have relatively small, short stipitate glands on abaxial surfaces more commonly than farther south, where they are more or less eglandular.</p><!--
--><p>Plants with the morphological features of <i></i>subsp.<i> sayi</i> also exist in eastern Siberia; confirmation of their identity depends on ploidy levels (W. H. Lewis 1958).</p><!--
--><p>Branches of <i></i>subsp.<i> sayi</i>, as well as of <i>Rosa nutkana </i>subsp.<i> macdougalii</i> and <i>R. woodsii </i>subsp.<i> ultramontana</i>, were used as cleansing agents and disinfectants, especially at times of illness and death, by the Shuswap people of interior British Columbia. The branches were placed around houses to prevent diseases in corpses from spreading to others; they were also used to disinfect rooms, clean air, and keep bad spirits away. People also used solutions made from rose bushes for steaming and cleansing in sweathouses. Root solutions were used to treat burns by soaking the burned area, which healed well without blistering or scarring. Hips and branches were boiled and decoctions drunk as medicine for treating diarrhea and upset stomach; teas made from branches were drunk to protect oneself from anything bad (N. J. Turner, pers. comm.).</p>
