|discussion=<p>O. E. Schulz (1927) recognized five varieties within <i>Draba pauciflora</i>, of which four were listed from North America. Schulz’s concept of <i>D. pauciflora</i> encompassed multiple taxa that we recognize as separate species, including <i>D. micropetala</i> and <i>D. subcapitata</i>. C. L. Hitchcock (1941) and R. C. Rollins (1993) did not mention <i>D. pauciflora</i>; the latter (and G. A. Mulligan 1974b) referred the North American material to D. adamsii.</p>
