--><p><i>Lepidium tiehmii</i> is known from mountain ranges in Douglas and Lyon counties. It was described and has been maintained (N. H. Holmgren 2005b) in Stroganowia, a genus now united with <i>Lepidium</i> (I. A. Al-Shehbaz et al. 2002) that otherwise is disjunct and restricted to the central Asian states of the Former Soviet Union and adjacent western China. In our opinion, the similarity of this species to those Asian ones formerly placed in Stroganowia is superficial and is the result of convergence rather than descent.</p><!--
--><p>The cotyledonary type was erroneously reported as conduplicate (R. C. Rollins 1993; N. H. Holmgren 2005b). In the several seeds that we dissected it was always incumbent.</p>
