|discussion=<p>R. T. Clausen (1975) noted significant differences among wild populations of <i>Rhodiola rosea</i> [as <i>Sedum</i> rosea] but found that most lost significance when the plants were grown together at Ithaca. He found that staminate plants outnumber pistillate by about 1.2–1.9 to 1 and that an occasional plant has both staminate and pistillate flowers in the same cyme. From meiosis in staminate plants A. Levan (1933) reported one bivalent as slightly heteromorphic and possibly a sex-chromosome pair of the XY type, but C. H. Uhl (1952) noted no heteromorphic bivalents. Roseroot has a long history as a medicinal plant; Clausen summarized what was known of its chemistry and its uses. The name “roseroot” is from the roselike odor of the dried rootstock.</p>
