|discussion=<p><i>Draba pedicellata</i> is known from Elko, Eureka, Nye, and White Pine counties in northeastern <i>Nevada</i> and to Tooele County in northwestern Utah. It was considered a variety of <i>D. cusickii</i> by R. C. Rollins (1993); chromosome number, morphology, and geographic distribution suggest a closer relationship to <i>D. sphaeroides</i>. For a detailed discussion and comparison of these species, consult M. D. Windham (2004). N. H. Holmgren (2005b) divided <i>D. pedicellata</i> into two varieties: var. pedicellata, which is found on limestone throughout the species range, and var. wheelerensis, which is found on non-calcareous substrates in White Pine County. Although var. wheelerensis has slightly more spreading pedicels on somewhat more flexuous rachises, it appears to be little more than a dwarf alpine form of the species.</p>
