|discussion=<p><i>Draba crassa</i> is easily recognized by its combination of fleshy, distinctly petiolate leaves with glabrous surfaces and mostly decumbent flowering/fruiting stems. N. H. Holmgren (2005b) indicated that it has 52 seeds per fruit (26 per locule), but in the plants we examined, the seed count did not exceed 20 per fruit.</p>
